Methyl vinyl thioketone

The in situ generation of methyl vinyl thioketone in refluxing pyridine provided each of the four possible mixed Diels-Alder products derived from 4w and 2w methyl vinyl thioketone participation in [4 + 2] cycloadditions with methyl vinyl ketone [Eq. (I)].3... [Pg.293]

Interestingly, no a,/3-unsaturated thiocarbonyl dimer and no products derived from the 27t thiocarbonyl participation in Diels-Alder reactions were observed although the potential, reversible generation of such products could not be ruled out. In contrast, the low temperature dimerization of a,j8-unsaturated thioketones including methyl vinyl thioketone, generated by flash vacuum pyrolysis (FVP), provided 1 derived from the clean, regiospecific Diels-Alder dimerization with 4tt and 2tt thiocarbonyl participation [Eq. (2)].4... [Pg.293]
