Two novel rare earth compounds have been synthesized using the previously reported (S)-MonoThioBINOL [(S)-H2-MTB], (S)-2-hydroxy-2?-mercapto-1,1?-binaphthyl). We have shown here that while the H-bonded complex containing TMG-H+ (tetramethyl guanidium cation) maintains the structure that the analogous BINOLate complex adopts, the complex with lithium cations in the secondary coordination sphere crystallizes as an ??ate? complex with an outer sphere lithium counter cation solvated by DME.

A series of N-aryl phosphoramidite ligands has been synthesized and applied to iridium-catalyzed allylic alkylation reactions, offering high regio- and enantioselectivities for a wide variety of substrates. These ligands feature the synthetic convenience and good tolerance of the ortho-substituted cinnamyl carbonates. Mechanistic studies, including DFT calculations and X-ray crystallographic analyses of the (pi-allyl)-Ir complexes, reveal that the active iridacycle is formed via C(sp2)-H bond activation.

The determination of the enantiomeric composition of chiral compounds by 1H, 13C, and 31P NMR spectroscopy in the presence of (S)-1,1′-binaphthyl-2,2′-diol demonstrated that the enantioselectivity of the method increases when the polarity of a solvent decreases as follows: CD3OD-D2O (4:1) < CD3OD < CDCl3 < CDCl3-CCl4 (1:1) < C6D6.The effect is caused by increase in stability of solvating agent-substrate complexes formed through the hydrogen bonds.Pantolactone, esters of substituted cyclopropanecarboxylic acids, amino alcohol propranolol, and 2,2'-bis(diphenylphosphinyl)-1,1'-binaphthyl were used as the substrates. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 18531-99-2, you can also check out more blogs about18531-99-2
