Wx. Gu et al., STUDIES ON MECHANISM OF REACTION OF DICHL OROCARBENE WITH TETRAPHENYLCYCLOPENTADIENONE, Gaodeng xuexiao huaxue xuebao, 18(2), 1997, pp. 238-241
The reaction of dichlorocarbene with tetraphenylcyclone (1) resulted i
n carbon monoxide and gem-dichloro compound (3) together with dichloro
oxirane (4) and adduct (5), The aromatic structure of carbonyl Ylide a
nd its twist geometry led to deoxygenation to be the main reaction pat
hway.
