  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.
