Abstract

Triethylmanganate (Et 3 MnMgBr) was also effective as tributylmanganate. However, trimethylmanganate derived from MnCl 2 and MeMgI was not effective for the transformation. For instance, treatment of 1f with Me 3 MnMgI gave a methylated product (1,4-pentanediol) in only 13% in addition to unidentified complex products. The use of n-Bu 3 MnLi derived from n-BuLi instead of n-BuMgBr afforded 2a in only 31% yield along with 3a (7%). ... Hexadecane could be detected in ...
