Abstract:

Methylenediboracyclopentanes I (R = Et, CHMe2) were prepd. by cyclocondensation of H2C:C[CH2BCl:NR2]2 in the presence of Na/K alloy. Reaction of I with lithium 2,2,6,6-tetramethylpiperidide or Me3CLi followed by cyclopentadiene gave II (R = Et, CHMe2, resp.). The x-ray crystal structure of I (R = CHMe2) was detd.
