Reactions of tert-butyl tetraethylphosphorodiamidite with benzylideneacetylacetone, benzylideneacetoacetic ester, and benzylidenemalonic ester are studied. It is shown that the reaction pathway significantly depends on ...

A series of binary catalysts based on oxides of zinc and variable-valence metals were tested in synthesis of 2-methylpyrazine by catalytic dehydrocyclization of 1,2-propylene glycol with ethylenediamine.
