Convergent synthesis of alpha -aryl- beta -ketonitriles

The present invention relates to processes for the production of alpha -aryl- beta -ketonitriles, which serve as synthetic intermediates in the preparation of a series of biologically important molecules such as corticotropin releasing factor (CRF) receptor antagonists.

Practical and efficient procedure for the in situ preparation of B-alkoxyoxazaborolidines. Enantioselective reduction of prochiral ketones

A new method for the in situ elaboration of B-alkoxyoxazaborolidines is presented. Their use in the enantioselective reduction of prochiral aromatic ketones provides excellent chemical and optical yields of chiral alcohols.

(Fluoroorgano)fluoroboranes and -fluoroborates I: Synthesis and spectroscopic characterization of potassium fluoroaryltrifluoroborates and fluoroaryldifluoroboranes

A convenient preparation of K[ArBF3] (Ar=2-C6H4F, 3-C6H4F, 4-C6H4F, 2,6-C6H3F2, 3,5-C6H3F2, 2,4,6-C6H2F3, 3,4,5-C6H2F3, 2,3,4,5-C6HF4 and C6F5) is offered and the IR and multinuclear NMR spectra of these salts are reported. Treatment of the trifluoroborate salts with BF3 in chlorocarbon solvents provides an easy synthetic route to the corresponding aryldifluoroboranes ArBF2. The multinuclear NMR spectra of ArBF2 are presented. The electron substituent effect of the [-BF3]--group shows this substituent as one of the strongest σ-electron donors, while its π-electron influence is negligible (σI=-0.32, σR=-0.07).

Catalyseurs pour la transformation de polydimethylsilanes en polycarbosilanes

The conversion of polydimethylsilanes into the corresponding polycarbosilanes has been studied using liquid monomeric catalysts such as B(OR)3 (R = Me, Pr, SiMe3) or the B-N bonded compounds: Me2BN(SiMe3)2 and B(NEt2)3.Using this route it is possible to obtain polycarbosilanes which are more stable than the Mark III synthesized by the Yajima route and have a smaller polydispersity.These precursors obtained at 380-400 deg C do not require the use of an autoclave.

Amine boranes. III. Propanolysis of pyridine boranes

The solvolysis kinetics in 1-propanol of a number of alkyl-substituted pyridine boranes was studied. The reactions were first order in amine borane. Linear variation of log k with pKa of the pyridinium ion was observed for groups of compounds with the same ortho substituents; steric enhancement of rate was attributed to 1.1 and 3.5 kcal./mole of strain relief in the transition state for one or two o-methyl groups, respectively. It was concluded that the solvolysis mechanism involves B-N cleavage in the slow step. It was found that the free energy of the transition state referred to the dissociation products was invariant with substitutions on the pyridine ring.
