C6H4 valence bond isomers: A reactive bicyclopropenylidene

(Chemical Equation Presented) The simple bicyclopropenylidene derivative 21b, stabilized by fusion into naphthalene, results from reaction of dimesitylcyclopropenone 20b with the 1-trimethylsilyl-1H-cyclopropa[d] naphthalenyl anion. Although unstable in air, the molecule survives ambient conditions long enough for separation and mass spectral characterization. Aerial oxidation of 21 b leads to 2,3-dimesitylanthracene-1,4-dione 22b whose X-ray crystal structure has been determined. While diphenylcyclopropenone 20a does not give identifiable products, the di-tert-butyl analogue 20c gives quinone 22c but in lower yield.

Studies in the cycloproparene series: 1 chemistry of the 1-trimethylsilyl-1H-cyclopropa[b]naphthalenyl anion

Desilylation of 1,1-bis(trimethylsilyl)-1H-cyclopropa[b]naphthalene 10 with tert-butoxide or hydroxide ion gives anion 9 as a highly reactive species. Formed with tert-butoxide 9 can be intercepted by iodomethane to give the 1-methyl-1-trimethylsilyl deri
