Abstract

Phosphines containing two N-bound pyrrolidine groups and one alkyl or aryl group have been prepared and shown to be unusually electron rich donor ligands when compared to either tris (N-pyrrolidinyl) phosphine or the trialkyl-or triaryl-phosphines. It is proposed that the electron donating ability of a pyrrolidine group towards phosphorus had been underestimated as only two pyrrolidinyl groups can donate towards the phosphine via the ...
