title: Direct observation of supported W bis-methylidene from supported W-methyl/methylidyne species.
abstract: Extensive solid-state NMR analyses unambiguously determine the formation of silica supported W bis-methylidene methyl species by reaction of the corresponding methyl carbyne with trimethylphosphine or a cyclic olefin.
