CROSS-COUPLIN REACTIONS BETWEEN SOME ALLYL, HOMOALLYL, AND HOMOPROPARGYL SUBSTRATES AND TRIALKYLALANES OR DIALKYL- AND DIARYL-MAGNESIUM DERIVATIVES

Article abstract of DOI:10.1016/0022-328X(85)87328-9

Trialkylalanes and dilkyl- and diaryl-magnesium derivatives can be cross-coupled with allyl ethers and esters, sulphides, and quaternized allylamines.The reactions proceed uncatalyzed either with mild conditions or in the presence of copper complex catalysts to result in high yields of mono- and di-olefins of various structures.The alkylation of homoallyl or homopropargyl tosylates by trialkylalanes is accompanied by cyclization, which leads to alkyl-substituted cyclopropanes. i.e. cyclobutanes and cyclopropylidenes.
