| —— | Z-3,4-dimethyl-5-[1-(4,4,5-trimethyl-3,4-dihydropyrrol-2-ylidene)-ethyl]-1H-pyrrole-2-carboxylic acid tert-butyl ester | 334474-10-1 | C20H30N2O2 | 330.47 |
Thioimidates 1-Z undergo facile cross-coupling with Pd(0)RZnI but are inert to Pd(0)R2Zn. This difference is due to the lower Lewis acidity of R2Zn, as opposed to lower nucleophilicity. Various sources of RZnI (R = Me, Et) and Pd(0) were evaluated for their convenience and reactivity.Key words: thioimidates, cross-coupling, dialkylzincs, alkylzinc iodides.
