Benzofused 1H-1,3-azaphospholes are lithiated at the N-atom by tBuLi but phosphinylation takes place at either the N- or the P-atom. Smaller chlorophosphines react at nitrogen, bulkier react at phosphorus. Substituents at C2 promote the latter mode. N- Substituted 2H-1,3-benzazaphospholes undergo CH-metalation or addition at the P=C bond, depending on the conditions, and allow access to 2-functionally substituted benzazaphospholes or their 2,3-dihydro derivatives, new sigma P-2,X or sigma P-3,X hybrid ligands (X=O,P).
