Reaction of diphenyl[2-(triethoxysilyl)ethyl]phosphine oxide with boron trifluoride etherate

Diphenyl[2-(trifluorosilyl)ethyl]phosphine oxide was synthesized by the reaction of diphenyl[2-(triethoxysilyl)ethyl]phosphine oxide with boron trifluoride etherate. As shown by the 1H, 13C, 19F, 31P, 29Si multinuclear NMR spectroscopy data, the silicon atom in the molecule is tetracoordinate. The absence of P=O→Si interaction in diphenyl[2-(trifluorosilyl)ethyl]phosphine oxide, as follows from the comparison of the calculated [GIAO B3LYP/6-311++G(2d,p)] and experimental δ(29Si) and δ(31P) values, is due to the formation of complex with BF3 by the phosphoryl oxygen.

Phosphorous silane coupling agent and preparation method thereof

The invention relates to a phosphorous silane coupling agent and a preparation method thereof and belongs to the technical field of a functional auxiliary agent. The method comprises the following steps: by taking diphenylphosphine (DPP) or diphenyl oxide phosphine (DPOP) or dimethyl phosphine (DMP) and vinyl silane coupling agent as raw materials, and by taking azo or peroxy substance as a catalyst or taking no catalyst, performing addition reaction on DPP, DPO or DMP and vinyl silane coupling agent under a certain temperature, and then collecting the phosphorous silane coupling agent from the reaction mixture after reacting for a period of time. The method provided by the invention has the characteristics of mild reaction condition, easiness in control, high repeatability, high yield, and the like, and is suitable for expanded production. As a novel phosphorous silane coupling agent, the phosphorous silane coupling agent compounded according to the invention not only can promote the compatibility of some inorganic fillers and high molecular materials but also is beneficial to the promotion of the heat stability of the composite material and the reduction of the combustion property of the composite material.

Organic photoredox catalysis for the oxidation of silicates: Applications in radical synthesis and dual catalysis

Metal free photooxidation of alkyl bis(catecholato)silicates with the organic dye 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyano-benzene (4CzIPN) allows the smooth formation of alkyl radicals. The latter can be efficiently engaged either with radical acceptors to provide homolytic addition products or in photoredox/nickel dual catalysis reactions to obtain cross-coupling products.
