Abstract

Abstract: 2-Silapyrans (1, 2-oxasilins) are synthesized by the pyrolysis of 1-disilanyl-4- methoxy-1, 3-butadienes via initial 1, 5-silyl migration to afford an intermediate l-sila-l, 3- butadiene. Diels-Alder reaction of the silapyrans and perfluoro-2-butyne does not lead to isolable adducts but rather leads to apparent extrusion of silanone (R, Si= O), which is trapped by a variety of reagents. Reaction of the silapyrans and maleic anhydride ...
