Notes:
Co-pyrolytic gas phase reactions of 1,2-dimethyl-1,1,2,2-tetra-(methoxy)disilane with conjugated 1-oxatrienes in a flow-reactor furnish, via intermediate methoxymethylsilylene, mixtures of diastereoisomers of 3-phenyl-1-oxa-2-silacyclohepta-4,6-dienes and 3-styryl-1-oxa-2-silacyclopent-4-enes, usually including smaller amounts of the corresponding 1-oxa-2-silacy-clopent-3-ene isomers. In co-pyrolysis with an analogous N-isopropylazatriene, five-membered rings were formed preferentially, and seven-membered isomers could not be detected by NMR spectroscopy. © 1995 John Wiley & Sons, Inc.
