On treatment with (trimethylstannyl)lithium in THF at -78°C, 1,4-dichlorobutadienes (4) gave the stereoisomeric 1,4-bis(trimethylstannyl)-1,3-butadienes (5-7). Compounds 5 and 7 may be converted to the corresponding 1,4-dilithio-1,3-butadienes (1 and 3) by treatment with excess methyllithium, while 6 and 7 may be converted to 1 by reaction with 1 equiv of methyllithium.
