P-phenyl C-aminophosphaalkenes 1 react with p-chlorobenzonitrile oxides at -20 degrees C leading to 1,2,4-oxazaphospholines 2, which are characterized by NMR and decompose slowly at room temperature. An experimental and theoretical study of their thermal evolution shows that the most probable mechanism involves the formation of an azaphospholine such as 10 which is unstable generating a phenyl phosphinidene. The latter polymerize quickly.
