Cuproussiloxane as two self-assemblies, Cu20O20Si10Me10R10 and Cu24O24Si12Me12R12, with catalytic property

Abstract

Cuproussiloxane (1) was prepared from the reaction of silanediol R(Me)Si(OH)2 (R = N(SiMe3)(2,6-iPr2C6H3)) and (CuMes)4 (Mes = 2,4,6-Me3C6H2). The prepared compound crystalizes into two self-assemblies: Cu24O24Si12Me12R12 ([(CuO)2Si(Me)R]12, 1a) and Cu20O20Si10Me10R10 ([(CuO)2Si(Me)R]10, 1b). 1a and 1b feature dodecagonal and decagonal prism X-ray structures, respectively. 1 was found to exhibit good to excellent activity for catalyzing the aerobic C–P cross-coupling reaction of terminal alkynes with H-phosphonates to form alkynylphosphonates (70–99% yields).
