Flash vacuum pyrolysis of (2-methoxy- and (2-methylthiobenzoyl)alkylidenetriphenylphosphoranes results in loss of Ph3PO and methyl radical; cyclisation of the resulting radical intermediates leads to benzofurans and benzothiophens in which the 2-substituents have undergone novel fragmentation processes.
