A binuclear guanidinate yttrium carbyne complex: unique reactivity toward unsaturated C-N, C-O and C-S bonds.

ABSTRACT: A guanidinato-stabilized binuclear yttrium carbyne complex [(PhCH₂)₂NC(NC₆H₃ⁱPr₂-2,6)₂]₂Y₂(μ₂-Me)(AlMe₃)₂(μ₄-CH) (1) was synthesized via C-H bond activation and its versatile reactivities were investigated. Complex 1 underwent σ-bond metathesis with PhSSPh and nucleophilic addition with PhCN to form the corresponding yttrium thiolate complex 3 and aza-allyl complex 4 respectively. Additionally, the rare yttrium carbide complex 5 was also prepared by treatment of complex 1 with S₈. Interestingly, in the reaction with PhNCS, the C[double bond, length as m-dash]S double bond was cleaved, followed by C-H bond activation to give the ytt
