The solvent-insoluble poly(phenylene sulfide) main chain was reductively cleaved by using triethylsilane as a hydrogen source under palladium/I c Hex catalytic conditions. After the reaction, benzene and bis(triethylsilyl) sulfide as a sulfide source were formed efficiently. This method could be operated on a gram scale.

Silane alcoholysis of triethylsilane (Et3SiH) with alcohol (ROH) with the help of CpFe(CO)2Me (1) has been achieved to produce triethylsilyl ether (ROSiEt3) under the thermal condition. For some alcohols, the iron complex
Dehydrogenative coupling of aromatic thiols with Et3SiH catalysed by N-heterocyclic carbene nickel complexes

A series of new tetramethylcyclopentadienyl-functionalised N-heterocyclic carbene ligands with different wingtip substituents have been prepared and characterised. These ligands have been successfully coordinated to nickel affording complexes of the general type (Cp*-NHCR)NiX (X = Cl, I). These well-defined nickel complexes selectively catalysed the coupling of aromatic thiols with Et3SiH to give the corresponding silylthioethers (RSSiEt3). The nickel complexes bearing ethyl, iso-butyl, and n-butyl wingtips displayed comparable catalytic efficiency, while the nickel complex bearing a methyl substituent on the wingtip was the worst performing catalyst.

A major advance in main-group chemistry in recent years has been the emergence of the reactivity of main-group species that mimics that of transition metal complexes. In this report, the Lewis acidic phosphonium salt [(C 6F5)3PF][B(C6F5) 4] 1 is shown to catalyze the dehydrocoupling of silanes with amines, thiols, phenols, and carboxylic acids to form the Si-E bond (E = N, S, O) with the liberation of H2 (21 examples). This catalysis, when performed in the presence of a series of olefins, yields the concurrent formation of the products of dehydrocoupling and transfer hydrogenation of the olefin (30 examples). This reactivity provides a strategy for metal-free catalysis of olefin hydrogenations. The mechanisms for both catalytic reactions are proposed and supported by experiment and density functional theory calculations.

[RuCl(PPh3)2(3-phenylindenyl)] (1) has been shown to be an efficient catalyst in thiol dehydrogenative coupling to give disulfides. Moreover, an efficient procedure for the preparation of silylthioethers and thioboranes is presented. Complex 1 demonstrated a great ability to catalyse the coupling of thiols with silanes and boranes under mild conditions with excellent results (turnover number up to 200).

, (2007/10/12)
PROBLEM TO BE SOLVED: To provide a cooling water supply method for a high-capacity transformer for suppressing the clogging of an RO film, preventing a reduction in the flow rate of new cooling water which is supplied to a cooling tower along therewith, reducing a pump output therefor, and realizing improvement in operation efficiency, and its apparatus. ?SOLUTION: In a cooling water supply method for allowing raw water supplied from a raw water supply source to pass through an RO film comprising a reverse osmosis membrane and thereby forming cooling water, and cooling a high-capacity transformer using the cooling water, an aqueous solution of a compound which has a germicidal action to the cooling water and damages the RO film is previously allowed to pass through the RO film. ?COPYRIGHT: (C)2008,JPOandINPIT ?

Thermal reaction of RSH with Et3SiH in the presence of a catalytic amount of CpFe(CO)2Me exhibited dehydrogenative S-Si coupling to give RSSiEt3. A plausible reaction mechanism is proposed involving an Fe(IV) complex with
REACTIONS OF TRIORGANOSILYLSULFENYL HALIDES WITH SOME NUCLEOPHILES

, p. 1 - 6 (2007/10/02)
The reaction of triorganosilylsulfenyl halides R3SiSX (R=Ph, Et; X=Cl, Br) with carbon-carbon double bonds, trialkyl phosphites, and organometallic reagents have been studied.With the first two nucleophiles the course of the reactions differed from that with organosulfenyl chlorides because of nucleophilic attack of halide ion on silyl group.
