1. The zeolite-containing catalysts ABFZ-3 and ABFZ-6 have a high activity in the alkylation of benzene with ethylene. 2. Amorphous and crystalline aluminosilicates that contain Ni (as Ni2+ and NiO) are polyfunctional catalysts for the alkylation of benzene with ethylene, and can direct the reaction toward the formation of predominantly sec-butylbenzene and ethylbenzene, or sec-butylbenzene and butenes.

The alkylation of benzene with (+)-2-chlorobutane (1) by Lewis acid catalyst gave stereospecifically (-)-2-phenylbutane (2) with inversion of configuration at low temperature for short reaction time.A lowering of the stereospecificity of the reaction was found to be partly due to the racemization of (+)-1- and (-)-2.

Photoinduced Decomposition of Peracetic Acid in Isopropylbenzene
Ogata, Yoshiro,Tomizawa, Kohtaro
, p. 2419 - 2420 (1980)
Irradiation of peracetic acid in isopropylbenzene with 254 nm and over 290 nm lights gave as aromatic products mainly t-butylbenzene, 2-phenyl-2-propanol, and 2,3-dimethyl-2,3-diphenylbutane.The yield of t-butylbenzene was higher in 254 nm photolysis than that with >290 nm, while the yield of hydroxylated aromatics, i. e., 2-phenyl-2-propanol, was much higher with >290 nm than that with 254 nm.The distribution of products was little affected by the intensity of light.These results are discussed by a mechanism involving radicals of different reactivity derived from peracetic acid decomposition.

A family of phosphite/phosphinite-thioether ligands have been tested in the Ir-catalyzed asymmetric hydrogenation of a range of olefins (50 substrates in total). The presented ligands are synthesized in three steps from cheap indene and they are air-stable solids. Their modular architecture has been crucial to maximize the catalytic performance for each type of substrate. Improving most Ir-catalysts reported so far, this ligand family presents a broader substrate scope, covering different substitution patterns with different functional groups, ranging from unfunctionalized olefins, through olefins with poorly coordinative groups, to olefins with coordinative functional groups. α,β-Unsaturated acyclic and cyclic esters, ketones and amides werehydrogenated in enantioselectivities ranging from 83 to 99% ee. Enantioselectivities ranging from 91 to 98% ee were also achieved for challenging substrates such as unfunctionalized 1,1′-disubstituted olefins, functionalized tri- and 1,1′-disubstituted vinyl phosphonates, and β-cyclic enamides. The catalytic performance of the Ir-ligand assemblies was maintained when the environmentally benign 1,2-propylene carbonate was used as solvent. (Figure presented.).
Activation of C-C Bonds via σ-Bond Metathesis: Hydroborenium-Catalyzed Hydrogenolysis of Cyclopropanes

High-valent transition metal or main group complex mediated σ-bond metathesis plays an important role in the activation of covalent H-E bonds. However, its involvement in the activation of C-C bonds has remained elusive. Here we describe direct hydroboration of the C-C bonds of cyclopropanes by a hydroborenium complex. Our mechanism study suggests this reaction operates through a σ-bond metathesis pathway. With this hydroborenium complex as a catalyst, hydrogenolysis of unfunctionalized cyclopropanes was achieved, which is unprecedented for homogeneous catalysts and provides an unconventional approach for C-C bond functionalization in the absence of metals.
