1,1-Dialkyl-4R-4-methoxy-1-sila(germa)cyclohexa-2,5-dienes are thermolyzed at 500–600°C to give the 1,1-dialkyl-1-sila(germa)cyclohexa-2,5-dien-4-ones and 1,1-dialkyl-4R-1-sila(germa)cyclohexa-2,4-dienes. If R = C(CH3)3, ketones are formed nearly exclusively but if R = C6H5 2,4-dienes are formed.
将1,1-二烷基-4R-4-甲氧基-1-sila(germa)环己-2,5-二烯在500–600°C下加热,得到1,1-二烷基-1-sila(germa)环己- 2,5-二烯-4-酮和1,1-二烷基-4R-1-sila(germa)环己-2,4-二烯。如果R = C(CH 3)3,酮几乎排他地形成,但如果R = C 6 H ^ 5 2,4-二烯构成。
