EVIDENCE FOR A CARBENE MECHANISM IN THE METAL—CHELATE ASSISTED DEHALOGENATION OF CHLOROFORM

Dehalogenation of chloroform in 50% chloroform-methanol (v/v) at 63°C is assisted by bis(N-n-butylsalicylaldiminato)nickel(II). The reaction was studied in the presence of cyclohexene, and nuclear magnetic resonance (NMR) spectra were evaluated at varying times for the appearance of 7,7-dichloronorc...

Zusammenfassung:Dehalogenation of chloroform in 50% chloroform-methanol (v/v) at 63°C is assisted by bis(N-n-butylsalicylaldiminato)nickel(II). The reaction was studied in the presence of cyclohexene, and nuclear magnetic resonance (NMR) spectra were evaluated at varying times for the appearance of 7,7-dichloronorcarane, the logical product of dichlorocarbene and cyclohexene. The NMR spectra indicate the formation of 7,7-dichloronorcarane, 7,7-dichlorobicyclo[4.1.0]heptane.
