  摘要：

  Allyl Mn(II)-organic compounds R1CH = C(R2).CH2MnCl (R1 = H, Me; R2 = H, Me, Bu, PhCH2) react with esters and nitriles of crotonic, trans-2-hexenoic, sorbic, cinnamic, maleic, fumaric, heptylidenemalonic, and trans-(2-butenylidene)malonic acids in THF at -78 to -60-degrees-C giving 1,4-addition products. A single diastereoisomer is formed in the case of MeCH = CHCO2Me and PrCH = CHCO2Me.

  The allyl Mn(II) organic compounds R1CH = C(R2)CH2MnCl (R1 = H, Me; R2 = H, Me, Bu), obtained in situ from Grignard reagents and Li2MnCl4, react with esters of 4-bromocrotonic, (2-bromobutylidene)-, (4-bromo-2-butenylidene)-, (2-bromoisobutylidene)malonic, and (2-bromoheptylidene)cyanoacetic acids in THF at -78 to +20-degrees-C to give derivatives of substituted cyclopropanecarboxylic or cyclopropane-1,1-dicarboxylic acids. These derivatives contain a fragment of the allyl type. When ethers of 2-(bromomethyl)acrylic, 4-bromo-2-methyl-, and 4-bromo-3-methyl-2-butenoic acids are used, cross-combination products result.
