    • (a) Interestingly, we observed that only one of two possible "vinylidenecarbene dimers", 9 (i.e., meso or d,l), was formed in this reaction. However, despite many attempts, we were unable to obtain a good-quality single crystal of this material for X-ray structural analysis. Hence, the identity of the single isomer formed in this reaction remains unestablished.

    • (b) When 6 was allowed to react with n-BuLi - THF in the absence of cyclohexene (trap), the isolated yield of 9 increased marginally (i.e., from 9% to 13%). In addition, 9 was obtained in low yield (6%) when 12 was allowed to react with LDA-THF in the absence of cyclohexene. When the latter reaction was performed in the presence of added cyclohexene, 9 was not detected among the reaction products.
