@Juan_RodCo @LatinXChem @marcoshrdz @iquimicaunam Muy bien, será interesante ver que organocatalizadores has usado, gracias!

@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"

@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.

@OrgSynLujanLab @LatinXChem Hello Armando! Higher energetic barriers in ethylene exchange and migratory insertion in catalyst 5a with respect to Brookhart type catalyst means a lower activity in ethylene polymerization compared with them.

@debo_oc @LatinXChem @AcSIR_India @csiriiim @csir_ncl 2) what about the reactivity with other substrates like cyclic (non-aromatic), aliphatic or just 1 ring instead indole fragment?

@debo_oc @LatinXChem @AcSIR_India @csiriiim @csir_ncl Hi Debojyoti, nice work. I have some curious questions about your work. 1)How can you explain the effect of MeOH or DMSO in conditions A and B? since you are obtaining 2 different heterocycles. However, in your scope by using DMSO you got the pyrrole instead pyridine.

@MannyCampos1998 @LatinXChem Hi Emmanuel, interesting work! Have you tried your catalyst with di-halogenated rings, for example, dichlorotoluene or 3,5 dichloroaniline? sometimes Pd catalyst is hard in these substrates.
