A series of chiral bifunctional squaric prolinol ligands, having N, S substituents at C(3) of the squaric ring were synthesized and applied to the asymmetric borane reduction of prochiral ketones via an in situ formed chiral boron heterocycle, affording secondary alcohols with high yields and excellent enantiomeric excesses (up to 99%). The crystal structure of 5a was obtained and the mechanism of the catalytic asymmetric reduction is also discussed.

An effective and easy-to-handle process for the desulfitative Suzuki cross-couplings of arylsulfonyl chlorides and boronic acids in the presence of a recyclable polymer-supported NHC-Pd complex was developed. The supported catalyst could be reused several times with little loss of catalytic activity.

A novel polymer-supported imidazolium salt has been prepared from a bisimidazolium salt and cross-linked chloromethyl polystyrene. The polymer-supported N-heterocyclic carbene-palladium complex, generated from the supported bisimidazolium salt and Pd(OAc)2, efficiently catalyzed the Suzuki coupling reaction of aryl bromides and arylboronic acids under air in aqueous DMF solution at room temperature, giving biaryls in good to excellent yields. The catalyst could be reused several times still retaining high activity.

Transmetallation of 2-tributylstannylbuta-1,3-diene with SnCl4 followed by Lewis base promoted addition of the resulting 1-trichlorostannyl-2,3-butadiene to aldehydes in the presence of DMF allows their buta-1,3-dienylation to take place at the C2 position with complete regioselectivity in high yields.

Novel cyclodextrin (CD) dimers (3a–c) linked by multidentate ligands were prepared by reacting 6- deoxy-6-(hydroxyethylamino)- -CD (2) with p- and m-bis(bromomethyl)benzene and 2,6-bis(bromomethyl)pyridine, respectively. The catalytic properties of 2, 3b and 3c in the hydrolytic cleavage of p-nitrophenyl alkanoates, namely acetate (PNPA), butanoate (PNPB), hexanoate (PNPH) and octanoate (PNPO), were examined. CD dimers 3b and 3c showed modest rate enhancements around neutrality. Although the catalytic rate constants (kc) in the presence of 3b or 3c did not vary significantly with the chain length of the esters, the Michaelis constants, KM, for 'long-chain' esters (PNPH and PNPO) were much smaller than those for 'short-chain' esters (PHPA and PNPB), and consequently the selectivity factors (kc/KM) for 'long-chain' esters were much larger than those for 'short chain' esters, indicating that the CD dimers had good dimensional recognition ability and substrate selectivity in the hydrolytic cleavage of pnitrophenyl alkanoates. Addition of Cu2 to the reaction media did not have much impact on KM, but led to an appreciable increase in kc, and therefore increases in kc/ku and kc/KM. The monomeric CD compound 2 showed essentially no selectivity in the hydrolysis of these esters. Kinetic consequences are briefly interpreted.

Four novel hexadentate imidazolium salts were synthesized from hexakis(bromomethyl)benzene and 1-substituted imidazole. The arylation of aldehydes with arylboronic acids was effected conveniently and in high yields by a catalyst system generated in situ from these hexadentate imidazolium salts, [Rh(COD)Cl]2 and a base.

A novel polymer-supported N-heterocylic carbene (NHC)-rhodium complex was prepared from chloromethyl polystyrene (CMPS) resin using a simple procedure. This polymer-supported NHC-rhodium complex was used as a catalyst for the addition of arylboronic acids to aldehydes affording arylmethanols in excellent yields.

【期刊论文】Efficient biphasic hydroaminomethylation of long chain olefins in ionic liquids†
罗美明, Ying Yong Wang, Mei Ming Luo, * Qi Lin, Hua Chen and Xian Jun Li
Green Chem., 2006, 8, 545-548,-0001,():

Hydroaminomethylation of long chain olefins with secondary amines was performed efficiently in ionic liquids 1-n-alkyl-3-methylimidazolium tosylates [Rmim][p-CH3C6H4SO3] (R = n-butyl, octyl, dedecyl, cetyl) with Rh-BISBIS (sulfonated 2,29-bis(diphenylphosphinomethyl)-1,19-biphenyl) complex as catalyst. High activity and selectivity for amines were achieved. The ionic liquid containing catalyst can be easily separated from product and re-used several times with only a slight decrease in activity.
