Macrocyclic sulphide synthesis: trithia[nn+1,2n+4][2n+ 1]metacyclophanes
Abstract
The formation of trithiametacyclophanes from the trisodium salt of a tris(mercaptoalkyl)benzene and a trisbromoalkylmethane is described. 1H N.m.r. spectra were used to determine the structures of the products, with the aid of shift reagents.
