Papers Abstract

The synthetic utility of adducts of 1,3-dipolarophiles with vinyl phosphonium salts.
3,3-Diphenyl-5-triphenylphosphinio-Δ1-pyrazoline bromide and 4-triphenylphosphonio-Δ1-pyrazoline bromide were prepared and generalized reactions for 1,3-dipolar adducts of vinyl phosphonium salts were suggested and illustrated using the aforementioned species.
