摘要

Abstract A series of five cyano (arylcarbamoyl) phosphorus ylides 2 and five cyano (arylthiocarbamoyl) phosphorus ylides 3 are prepared and fully characterized. Pyrolytic reaction products of a representative example of each type obtained by flash vacuum pyrolysis technique show that they undergo thermal extrusion of Ph 3 PO or Ph 3 PS. Kinetic study of the gas-phase pyrolysis of each ylide by static method shows that these reactions ...
