ITQ-40, New Crystalline Microporous Material

ITQ-40 (INSTITUTO DE TECNOLOGíA QUíMICA number 40) is a new crystalline microporous material with a framework of tetrahedral atoms connected by atoms capable of bridging the tetrahedral atoms, the tetrahedral atom framework being defined by the interconne

Studies on the efficient generation of phosphorus-carbon bonds via a rearrangement of PIII esters catalysed by trimethylhalosilanes

Halotrimethylsilanes Me3SiX (X = Br, I) catalyse rearrangements of tricoordinate phosphorus esters R′R″P-OR into the corresponding phosphoryl systems R′R″P(O)R. This provides a simple and efficient route to a variety of structures containing phosphorus-carbon bonds, under mild conditions and with good yields. The reaction mechanism was investigated in detail by 31P NMR spectroscopy and independent synthesis of the reaction intermediates. It has been demonstrated that the primary products of this catalytic reaction are halogeno PIII structures R′R″PX and silyl ethers ROSiMe3 and that they subsequently react to give the corresponding phosphorus silyl esters - Me 3SiOPR′R″-and alkyl halides RX. At higher temperatures these intermediates then react to form R′R″P(P)R compounds. This paper also features the surprising observation that when esters Ph 2POR and halotrimethylsilanes Me3SiX (X = Br, I) are used in 2:1 ratio, phosphonium salts Ph2R2P+X - and trimethylsilyl diphenylphosphinate - Ph2P(O) OSiMe3 - are formed as the major products. Experimental evidence indicates that the mechanisms of both reactions are fundamentally different from that of the Michaelis-Arbuzov reaction. Me3SiCl is not reactive and this paper explains why.

Kinetics of Alkaline Hydrolysis of Quaternary Phosphonium Salts. The Influence of Aprotic Solvents on the Hydrolysis of Ethyl(phenyl)phosphonium Iodides.

Third-order rate constants have been determined for the hydrolyses of the ethyl(phenyl)phosphonium iodides (1) in aqueous methanol and in aqueous tetrahydrofuran.The very large increase in the rate of hydrolysis of tetra- and tri-arylphosphonium salts which is induced by the addition of tetrahydrofuran to the medium drops to almost zero for tetra- and tri-alkylphosphonium salts.This is attributed to an increase in the delocalisation of the positive charge in phosphorus, which leads to less specific solvation of the alkylphosphonium ions.
