Synthetic methodology using tertiary phosphines as nucleophilic catalysts
Abstract:
Allenoates or 2-alkynoates are known to react with tertiary phosphines to form the phosphine-substituted 1,3-dipoles, which can react with various substrates with the simultaneous elimination of the tertiary phosphine. The reaction is catalytic to the tertiary phosphine used. The investigation of the appropriate dipolarophiles and the further extension of this reaction are discussed.
