The present invention relates to a highly efficient process to prepare alkyl and vinyl phosphines which are useful as starting materials for novel bisacylphosphine oxides, bisacylphosphinic acids, salts, and derivatives thereof each bearing a vinyl functionality bound to the phosphorous atom as well as a versatile process for the preparation of the latter.

The thermolysis of 1-vinylphosphirane 5 at 700°C yields phosphapropyne 7; owing to the existence of an equilibrium between divinylphosphine 6 and 1-vinylphosphirane above 500°C, the same phosphapropyne is also obtained by thermolysis of divinylphosphine.
