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.
