A study of the reactions of 1,3-diynes with organo-cuprates and -argentates
Kleijn, H.,Tigchelaar, M.,Meijer, J.,Vermeer, P.
, p. 337 - 341 (2007/10/02)
1,3-Diynes HCC-CC-R' (1, R'= H or Ph) are converted by cuprates M' (R = alkyl; Y = Cl, Br or R; M'= Li, MgCl or MgBr) into a mixture of C-R'>M' (2) and C-R'>M' (3).When R is n-alkyl, adducts 2 are the major pr
