The synthesis and olefin polymerization behavior of a series of new phosphine-iminoquinoline iron complexes is described. Upon activation, the iron complexes are highly active for ethylene polymerization, producing low molecular weight (MW) linear polyethylene (PE) with activities up to 108 g of PE/((mol of Fe) h). This activity is comparable to that of the most active bis(imino)pyridine iron catalysts and heterogeneous Ziegler-Natta catalysts. The MWs and molecular weight distributions (MWDs) of the resulting polymers can be controlled by the modification of the catalyst structures. In addition, upon activation the iron complexes are capable of copolymerizing ethylene with 1-octene, giving copolymers with alpha-olefin incorporation up to 8.8%.

METHOD FOR PRODUCING ALCOHOL BY HYDROGENATING LACTONE AND CARBOXYLIC ACID ESTER IN LIQUID PHASE

Disclosed is a method for producing an alcohol from a lactone or a carboxylic acid ester, which enables to produce an alcohol from a lactone or a carboxylic acid ester under relatively mild conditions with high yield and high catalytic efficiency. This method also enables to produce an optically active alcohol from an optically active lactone or an optically active carboxylic acid ester. Specifically disclosed is a method for producing an alcohol by hydrogen reducing a lactone or a carboxylic acid ester in the presence of a catalyst containing ruthenium and a phosphine compound represented by the following general formula (1): wherein R1 represents a spacer; R2, R3, R4, R5, R6 and R7 independently represent a hydrogen atom, an alkyl group having 1-12 carbon atoms, an aryl group or a heterocyclic group; and R8, R9, R10, R11, R12 and R13 independently represent an alkyl group having 1-12 carbon atoms, an aryl group or a heterocyclic group.

Recent advances in electrophilic CF3-transfer using hypervalent iodine(III) reagents

The development of new methodologies for an efficient introduction of CF3 groups into complex molecules constitutes one of the most challenging tasks of modern organic chemistry. Recently, we reported the access to a new class of electrophilic CF3-transfer reagents based on hypervalent iodine. The versatile application of these reagents to C-centred nucleophiles, such as beta-keto esters, silyl enol ethers and alpha-nitro esters, as well as to thiols and primary and secondary phosphines is described. Experiments with phenols afforded corresponding trifluomethylethers in very low yields. Schweizerische Chemische Gesellschaft.

Pseudo enantiomeric mixed S/P ligands derived from carbohydrates for the 1,4-addition of phenyl boronic acid to cyclohexenone

The application of phosphinite-thioglycosides and phosphine-thioglycosides ligands in Rh(i)-catalyzed 1,4-addition of phenylboronic acid to cyclohexenone is reported. Among the ligands tested, phosphinite-thioglycoside 3 and phosphine-thioglycoside 10, bearing a 1,2-cis arrangement of the two heteroatoms, have exhibited the best results in terms of reactivity and enantioselectivity. Interestingly, ligands 3 and 10, both derived from a d-sugar are able to generate the addition product of the phenylboronic acid to the cyclohexenone with opposite configurations, behaving thus as enantiomers.
