The first preparation of disilene via reductive dehalogenation of 1,2-dichlorodisilane: the formation of an unusual air-oxidation product, 1-oxa-2-silacyclopent-3-ene-derivative
The most air-stable disilene, tetrakis(2,4,6-triisopropylphenyl)disilene, again was obtained by the reaction of 1,2-dichloro-1,1,2,2-tetrakis(2,4,6-triisopropylphenyl)disilene with lithium naphthalenide. The disilene afforded its air-oxidation product having 1-oxa-2-silacyclopent-3-ene framework which was determined by X-ray analysis.
