For compounds 1\u201312 different alkyl radical and alkene losses and the cleavage of the P\u2013heteroatom bonds, instead of the P\u2013C bonds, were representative and dependent mainly on the substitution on the N and P atoms.

Only slight differences were found between some of the corresponding isomers, but interestingly the compounds formed clear groups on the basis of the differences in their fragmentation, depending on the ring\u2010N and ring\u2010P substituents.
