Molecular radical cations of oxazole (1) and isoxazole (2) dissociate by losing carbon monoxide or a hydrogen atom, respectively.These fragmentations were examined by use of tandem mass spectrometry, flash vacuum pyrolysis and ab initio molecular orbital calculations.A multi-step mechanism is proposed which incorporates these new experimental and theoretical data.The case of methylated homologues of 1 and 2 is also considered.

Reaction of Grignard reagents with isopropylidene bis(methylthio)methylenemalonate (1) resulted in conjugate addition to give an intermediate 2, which could either be hydrolyzed to an isopropylidene (1-methylthioalkylidene)malonate 3 or reacted with ammon
