A tetranuclear diphenyltin(IV) complex and its catalytic activity in the aerobic Baeyer-Villiger oxidation of cyclohexanone

The synthesis and crystal structure of the new tetranuclear diphenyltin(IV) compound [{SnPh2}{SnPh2(OCOMe)}(μ2-OMe)(μ3-O)]2 (1), generated from the reaction of [SnPh2Cl2] and NaOCOMe, are described. Single crystal X-ray diffraction revealed that 1 is a tetranuclear complex with four diphenyltin(IV) units which are inter-connected by μ3-oxido and μ2-methoxido bridges leading to a ladder-like Sn4O4 cluster. Structural comparison with related...
