Rings containing two CC units flanked on either side by Me 2 Si units have been obtained by twofold coupling of the reactants 1 (n = 0–4) and 2 . Mutual reaction of two (→ 3 ) pairs of reactants is preferred, but reactions of three or four pairs are not unknown. When n = 3, 4, traces of seven‐ and eight‐membered cyclo ‐[Me 2 Si(CH 2 ) n SiMe 2 CC] species, respectively, are also formed.
