Synthesis and Photochemistry of Tris(trimethoxysilyl)acyl-silanes and 1,4-Tetrakis(silyl)-1,4-bisacylsilanes.

ABSTRACT: In this contribution, we present the synthesis of two groups of novel acylsilanes 1-6. Compounds 1 and 2 represent tris(trimethoxysilyl)acylsilanes, and compounds 3-6 are 1,4-tetrakis(silyl)-1,4-bisacylsilanes. All isolated compounds were characterized by infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy and X-ray crystallography. Additionally, these compounds were further analyzed by ultraviolet/visible (UV/vis) spectroscopy and their longest wavelength absorption bands were assigned by density functional theory (DFT) calculations. On the basis of the well-known Brook rearrangement of acylsilanes, we irradiated 1-6 in benzene solutions at 405 nm (λ) for several hours. Photolysis of compounds 1 and 2 afford
