The controlled synthesis of poly(3-hexylthiophene)s (P3HTs) with number-average molecular weights (Mns) up to 350 kg mol(-1) has been realized with Ni(IPr)(acac)2 as the catalyst.

The discovery of new strategies that emulate nature!s capacity to rapidly construct architectural complexity continues to be a central focus for research and development in the chemical sciences. Recently, our laboratory disclosed the concept of organocascade catalysis, a new chemical paradigm that combines two modes of catalyst activation (iminium and enamine catalysis) into one mechanism, the...

To begin to build an understanding of the interactions of CYP2B6 with substrates, two different 3-dimensional quantitative structure activity relationship (3D-QSAR) models were constructed using 16 substrates of B-lymphoblastoid expressed CYP2B6. A pharmacophore model was built using the program Catalyst, which was compared with a partial least-squares (PLS) model using molecular surface-weight...

Three- and four-dimensional quantitative structure activity relationship (3D/4D-QSAR) pharmacophore models of competitive inhibitors of CYP2D6 were constructed using data from our laboratory or the literature. The 3D-QSAR pharmacophore models of the common structural features of CYP2D6 inhibitors were built using the program Catalyst (Molecular Simulations, San Diego, CA, USA). These 3D-QSAR mo...

Asymmetric transfer hydrogenation (ATH) is an important catalytic process in the fragrance and pharmaceutical industries. The Noyori–Ikariya chiral molecular ruthenium complex has been catalyst...

The chromium/vanadium bimetallic Phillips catalysts developed by our research group have been proved to be a promising process to produce bimodal polyethylene using a single-reactor process. The vanadium loading of CrV-1/1, CrV-1/2, and CrV-1/3 has a significant effect on the polymerization activity, product molecular weight (MW), as well as th...

Cyclopentadienyl-titanium complexes containing –OC6H4X ligands (X = Cl, CH3) activated with methylaluminoxane (MAO) were used in the homo-polymerization of ethylene, propylene, 1-butene, 1-pentene, 1-butene, and 1-hexene, and also in copolymerization of ethylene with the α-olefins mentioned. The -X substituents exhibit different electron donor-acceptor properties, which is described by Hammett’...

Manganese oxide octahedral molecular sieves (OMS-2) could act as an efficient, reusable heterogeneous catalyst for transformation of various primary amines to the corresponding primary amides through the sequence of oxidative dehydrogenation and successive hydration.

Semicrystalline microparticles of high molecular mass polyethylene can be prepared as aqueous dispersions by catalytic emulsion polymerization of ethylene with a mini-emulsified catalyst precursor (D$\rm{\frown}$D=salicylaldimine, L=pyridine). Stable polymer latexes are formed.

Carbon molecular sieve membranes (CMSMs) are an important alternative for gas separation because of their ease of manufacture, high selectivity due to molecular sieve separation, and high permeance. The integration of separation by membranes and reaction in only one unit lead to a high degree of process integration/intensification, with associated benefits of increased energy, production effici...
