Abstract

Reactions of P(MeNCH2CH2)3N, a new powerfully basic pro-azaphosphatrane, are discussed. Some of these reactions, such as oxidation with chalcogens and adduct formation with BH3 and CS2 lead to pro-azaphosphatranes in which the phosphorus has become formally tetracoordinate. Other reactions, such as protonation or oxidation followed by BF3 adduct formation leads to HP(MeNCH2CH2)3N+ and F3BOP(MeNCH2CH2)3N, respectively, which possess phosphatrane structures featuring five-coordinate phosphorus.
