The first example of copper-catalyzed direct formylation of alkenyl C-H bonds for the facile synthesis of α,β-unsaturated aldehydes has been developed. This transformation has demonstrated high reactivity, mild reaction conditions and a broad substrate scope. BrCHCl2 is expected to be developed as an efficient stoichiometric C1 building block in organic synthesis.

A half-sandwich 1,2-azaborolyl (Ab) ruthenium complex, (Ab-CCPh) RuCl(PPh3)2 (1), has been synthesized by treating RuCl2(PPh3)3 with lithium 1,2-azaborolide L-1, or by treating either RuCl2(PPh3)3 or RuHCl(PPh3)3 directly with 1,2-azaborole LH-1. It is evaluated as a suitable precatalyst in [2 + 2] cycloadditions of norbornene derivatives with DMAD and in atom transfer radical additions of halogenated compounds with olefins.

Preparation of Various 1,1-Dihalo-2-haloalkylcyclopropanes and 1,1,2-Trihalocyclopropanes and their Reduction to Dihalides using Tributyltin Hydride

The title compounds, most of which were obtained by dihalocarbene addition to the corresponding alkenes, are generally reduced to dihalides in good yields. 1,1-Dichloro-2-chloromethyl-2-methylcyclopropane and all the tribromides investigated are attacked regioselectively at the gem-dihalo moiety, yielding isomeric mixtures of 1-halo-2-haloalkylcyclopropanes.Trihalides containing both bromo and chloro substituents are always attacked at the C-Br bond; as a consequence substituted 2-bromomethyl-1,1-dichlorocyclopropanes undergo ring opening and form 4,4-dichloro-1-butene derivatives.
