An alternative approach to alkylidene carbenes uses the deprotonation or halogen-lithium exchange of vinyl haUdes. Hence, treatment of the vinyl chloride 103 with potassium hexamethyldisilazide (KHMDS) resulted in the formation of the cyclopentene 104 via the intermediate alkylidene carhene (4.83). The carbene...
