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 invention relates to the use of heterocycles containing trivalent phosphorus as a ring member as catalysts for isocyanate modification and to a process for preparing polyisocyanates of the trimer type.
