Zatímco reakce 1 s CO vede selektivně k novému přímému spojení a produktu štěpení CO 2 ze dvou molekul 1 a čtyř molekul CO, reakce 1 s 2,6-dimethylfenylisokyanidem poskytuje pouze molární 1: 2 spojovací produkt 3 hlava-ocas s vazbou SiC.

eng	Homocoupling of CO and isocyanide mediated by a C,C '-bis(silylenyl)-substituted ortho-carborane	The unexpected reactivity of the o-carborane supported bis-silylene [(LSi:)C](2)B(10)H(10)1 {L= PhC(tBuN)(2)} towards carbon monoxide and 2,6-dimethylphenyl isocyanide is reported. While the reaction of 1 with CO leads selectively to the novel head-to-head coupling and C-O cleavage product 2 from two molecules 1 and four molecules CO, the reaction of 1 with 2,6-dimethylphenyl isocyanide affords solely the 1 : 2 molar head-to-tail coupling product 3 with a SiC bond.	2-coordinate; silylene; isonitriles; activation; monoxide; elements
