Substitution reactions in dinuclear molybdenum(III) thiolato-complexes induced by isocyanato ligands

The reactions of [Cp′ 2Mo 2(CO) 4(μ-SR) 2](BF 4) 2 with azido compounds proceeds via a mechanism analogous to the Curtius rearrangement to afford isocyanate species [Cp′ 2Mo 2(NCO)(CO) 3(μ-SR) 2](BF 4) (Cp′=C 5H 5, R=Me 1, Ph 2; Cp′=C 5Me 5, R=Me 3). Thermal substitution of CH 3CN or R′NC (R′= t-Bu,...

Description
Summary:The reactions of [Cp′ 2Mo 2(CO) 4(μ-SR) 2](BF 4) 2 with azido compounds proceeds via a mechanism analogous to the Curtius rearrangement to afford isocyanate species [Cp′ 2Mo 2(NCO)(CO) 3(μ-SR) 2](BF 4) (Cp′=C 5H 5, R=Me 1, Ph 2; Cp′=C 5Me 5, R=Me 3). Thermal substitution of CH 3CN or R′NC (R′= t-Bu, xylyl, benzyl) for CO in 1– 3 results in the formation of monosubstituted derivatives [Cp′ 2Mo 2(NCO)(CO) 2(L)(μ-SR) 2](BF 4) (L=CH 3CN: Cp′=C 5H 5, R=Me 4, Ph 5 ; Cp′=C 5Me 5, R=Me 6 ; L=R′NC: Cp′=C 5Me 5, R=Me, R′= t-Bu 7, xylyl 8, benzyl 9).
