From SiSi to SiC : Silyl‐anion‐substituted silene 2 was synthesized as air‐ and moisture‐sensitive yellow crystals by the reaction of the disilenyl lithium derivative 1 with adamantanone (see scheme). The physical properties of 2 suggest a silene‐type structure containing a silicon–carbon double bond, with no contribution from 1,2‐disilaallyl‐anion‐type and disilene‐type structures.
