Bis(dialkylamino)carbenium salts [(Me2N)2CCl]+}2MCl42− (M=Ni, Pd) and [Me2NC(X)NR2]+}2PtCl62− (R=Me, All; X=H, Cl, Me) are efficient catalysts for hydrosilylation of allyl phenyl ether, triallylamine, allyl chloride, allylamine, and 1-octene with various hydrosilanes. The catalytic activity is dependent on the salt composition and the nature of the metal M, the saturated compound, and the hydrosilane
Preparation of polysilsesquioxane reverse osmosis membranes for water desalination from tris[(ethoxysilyl)alkyl]amines by sol–gel process and interfacial polymerization
(PSQ)-based reverse osmosis (RO) membranes have been studied for water desalination. In this work, RO membranes were prepared from tris[3-(triethoxysilyl)propyl]amine (TTESPA), tris[3-(diethoxymethylsilyl)propyl]amine (TDEMSPA), tris[(triethoxysilyl)methyl]amine (TTESMA) tris[(triethoxysilyl)propenyl]amine (TTESP2A), and tris[3-(triethoxysilyl)prop-2-ynyl]amine (TTESP3A) by the sol–gelprocess and interfacial
