- 中文摘要: 9-Chlorobicyclo [ 6.1.0 ] non-1(9)-ene (4), a 2- chlorinated 1,3-fused cyclopropene, is synthesized and isolated from the dehalogenation of the 1-bromo-9,9- dichlorobicyclo [ 6.1.0 ] nonane, itself derived from cyclooctene. Compound (4) undergoes ring opening reaction to generate cyclooctenyl chlorocarbene (9) which reacts with water via conjugate addition and ipso-addition to give (E)- 2-(chloromethylene) cyclooctanol and cyclooctene-1- carboxaldehyde, respectively. The conjugate addition of (9) with water is more favorable than the ipso-addition by 3:1. Compound (4), which is stable at -25.degree.C for weeks without any decomposition, reacts with oxygen to produce 2- chlorocyclonon-2-enone via the ring-opening reaction adduct, vinyl alkylcarbene.
