Alkoxychlorocarbenes (ROCCl, R = benzyl, cyclohexyl, and 1-octyl) were generated from the corresponding diazirines in acetonitrile, dichloroethane, benzene, cyclohexane, and pentane solutions at 25°C, and the fragmentations of these carbenes were studied. A prominent product was phenacyl chloride (PhCH2CoCl), a formal rearrangement product of the carbene. In polar solvents, the two fragmentation transition states for CH3OCCl and C2H5OCCl were stabilized to the point where cis-trans isomerization, loss of CO, and concerted loss of CO + Cl all have similar activation energies. In less polar solvents, such as dichloroethane, heterolytic cleavage was probably not competitive.
