Reversible Carbonylation of an [NCN]PtMe Pincer Complex and Direct Evidence of Alkyl Migration

[NCN]PtMe (1) reacts with CO initially to form an adduct (2) and then again to form a carbonyl acyl complex (3). Reaction of 3 with Me3NO generates 2 by alkyl migration rather than carbonyl deinsertion.

[NCN]PtMe(1) 首先与一氧化碳（CO）反应生成加合物(2)，随后可再次发生反应，得到羰基酰基配合物(3)。化合物(3)与三甲基氮氧化物（Me3NO）反应时，通过烷基迁移路径生成产物(2)，而非经由羰基脱插入反应路径。
