Abstract Reaction of trialkyl phosphites with C= X electrophiles (aldehydes, ketones, ketophosphonates, aldimines, ketimines, isocyanates, isothiocyanates, and activated olefins) in the presence of amines and anilines hydrohalides was studied. We found that pyridine hydrohalides effectively activate the reaction of tralkyl phosphites with various C= X electrophiles: aldehydes, ketones, ketophosphonates, aldimines, ketimines, isocyanates, ...
