  Spectral study of interaction between allyl ethers and hydrosiloxanes

  摘要：

  Interaction of allyl ethers with hydrosiloxanes in the presence of metal complexes has been investigated by spectral methods (H-1 NMR, IR, and GC-MS) as well as by gas-liquid chromatography. It has been shown that the anti-Markovnikov addition predominantly occurs in the studied cases; disproportionation of siloxanes and migration of double bond in the ethers have been identified as side reactions. The tendency to enter the side reactions has decreased in the following series: (HMeSiO)(4) > HMe2Si(OSiMe2)(2)H a parts per thousand HMe2SiOSiMe3 > (HMe2Si)(2)O > (Me3SiOSiMeH)(2)O. The general scheme of disproportionation of siloxanes HMe2Si(OSiMe2) (n) H (n a parts per thousand yen 1) has been proposed. According to mass spectrometry data, the silicon-containing fragment majorly contributes to the fragmentation of hydrosilylation products. Fragmentation of the gamma,gamma-adducts is similar to that of gamma-adducts. The predominant direction of fragmentation in the products of beta,gamma-addition of HMe2Si(OSiMe2)nH (n = 1-3) to allyl ethers is determined by fragmentation of the gamma-component of the molecule. The scheme of fragmentation of the hydrosilylation products ions has been proposed.

The excimers contribution into the total fluorescence spectrum decreases with increasing siloxane linker length. The parallel-sandwich conformation of intramolecular pre-excimers formed by two terminal DBMBF2 moieties is confirmed by DFT-based calculations.
