@IsaacV_UG @LatinXChem Congrats, Darien! Regarding on the N "ranking" of the ylides, I’m curious how an ylide derived from a sulfinate would rank. Keep up the great work! :)

Hola, @LatinXChem, este es mi trabajo "Interacción Entre Iluros Útiles en la Reacción de Polihomologación". #LatinXChem24 #LatinXChemComp #Comp064 #DFT #Boron #ReactionMechanism #Ylides

@amcscheuer @LatinXChem These are great news! It's fantastic that your method shows no interference with other pesticides/herbicides and can also distinguish other relevant species. Keep up the great work!

@OrgSynLujanLab @LatinXChem (2/2) Currently, we are testing with AMPA, a metabolite of glyphosate, which can be distinguished in the colorimetric detection due to the absorption band of the formed product.

Hi @LatinXChem, presenting my work 'Derivatization of Glyphosate: A Kinetic Approach for Efficient Colorimetric Detection' at #LatinXChem24 #LatinXChemOrg #Org086 @LatinXChem #glyphosate #organophosphates #ChemPhysChem

@anahi_frs @LatinXChem Thank you for your reply, América. Keep up the great work, and I look forward to seeing your results once they're published. Regards!

@alex16rod @LatinXChem Thank you very much for the replies. Keep up the good work!

@OrgSynLujanLab @LatinXChem That’s correct. The linear part of the molecule is flat; however, a dihedral angle of 29° is observed for the benzoxazole ring. (3/3)

Hi @LatinXChem, presenting my work "Extensión de la conjugación de 2-arilbenzoxazoles mediante reacciones de acoplamiento cruzado de Sonogashira con 4,7-dietinilbenzotiadiazol" at #LatinXChem24 #LatinXChemOrg #Org046 #Sonogashira #NMR #Fluorescence #DFT #Organicsemiconductors

@mvs9018 @LatinXChem Thank you very much for the reply!

@OrgSynLujanLab @LatinXChem We are trying to avoid heating since hydrogen peroxide can be explosive.

Hi @LatinXChem, here I share with you my work titled "Catalyst-free oxidation of aldehydes through hydrogen peroxide and Wood's lamp". #LatinXChemOrg #Org090 #Oxidation #Photoox #H2O2

@AlbertoFel87398 @LatinXChem Awesome, thank you very much!

@OrgSynLujanLab @LatinXChem Yes, it’s an interesting exploration over energetic barrier in these kinds of catalysts. However, we keep looking for more active catalysts that can form longer polymer chains with ultra-high molecular weight, which would show better properties (mechanical, thermostable, etc.)

Hi @LatinXChem, I am happy to share my work "Mechanistic studies of Palladium (II)-electron rich complexes" @LatinXChem; #LatinXChem24; #LatinXChemOrg; #Org012

@anahi_frs @LatinXChem Hello América, this is Armando Luján from Cinvestav MX. Your research is super interesting and highly relevant given the region's agricultural output. How does the activity of your antifungals compare to the agroindustry leaders in treating infections caused by these fungi?

@QuirinoSauret @LatinXChem Thank you Quirino!

@OrgSynLujanLab @LatinXChem Normalmente la chalconas ha presentado actividades farmacológicas de mucho interés, al sustituir los fenilos por hererociclos, creemos que se pueda dar una mejor interacción con las dianas celulares. Para corroborarlo se tiene que realizar estudios in silico.

Hola @LatinXChem, les presentó mi trabajo titulado "Síntesis de heterochalconas en medio acuoso y su efecto toxicológico frente a Artemias Salinas" #LatinXchem24 #LatinXChemOrg #Org008 #quimicaorganica #chalconas #DACB #UJAT

@alex16rod @LatinXChem I noticed that in compound 4, the methoxy group (at the top) is orthogonal to the plane, which seems like a local minimum. Did you try making it coplanar with the aryl ring to see if it resulted in a better minimum?

@alex16rod @LatinXChem Hi Alexis, Armando Luján from Cinvestav MX here. Great molecules! Would extending conjugation via the oxygenated function in the anisole ring be useful? Also, are species 4 and 5 fully planar? (I see some dihedral distortion for the benzoxazole, am I right?

@AlbertoFel87398 @LatinXChem So, I suppose this isn’t a bad result, right? This would lead to shorter, more tunable polymeric chains, correct? Or were you aiming for more active catalysts?

@OrgSynLujanLab @LatinXChem Although catalyst 5a is bulkier than the previously reported Brookhart-type (which favors larger polymer chains), the electronic effects are playing a more significant role. These findings are helping us to design more efficient catalysts for ethylene polymerization.

@CarlosAngel92 @LatinXChem Hello Carlos, this is Armando Luján from Cinvestav MX. Beyond the general interest in expanding chemical space by combining an amino acid with an indole, is there a specific reason why attaching an indole to the carboxylate end of an amino acid is particularly important?

Hola @LatinXChem y a todos los participantes. Mi nombre es Carlos Ángel Jijón. Muy Felizmente les presento mi trabajo "Ciclación azida-alquino: una herramienta para funcionalizar aminoácidos con indoles". #LatinXChem24 #Org044 #LatinXChemOrg #Químicaclick #Ciclaciónalquinoazida
