一般說明

2-Butene is an alkene. All-silica zeolite RUB-41, containing 8- and 10-membered rings, is reported to be capable of separating trans-2-butene and cis-2-butene from 1-butene. Asymmetric gydrozirconation of cis- and trans-2-butene is reported. Stereospecific addition of methylene to trans-2-butene is reported to afford trans-1,2dimethylcyclopropane while similar addition to cis-2-butene affords cis-1,2dimethylcyclopropane.

A new class of polymer-supported (R,S)-BINAPHOS 1e in which the parent BINAPHOS has two alkoxy-substituents at the 3-positions of the phenyls, has been synthesised. Using its Rh(I) complex, asymmetric hydroformylation of olefins proceeded with higher enantioselectivity in some cases compared

The reactivation of organophosphorus compound (OP)-inhibited acetylcholinesterase (AChE) by oximes is inadequate in case of different OP nerve agents. This fact led to the synthesis of numerous novel oximes by different research groups in order to identify more effective reactivators.
