Living polymerization of substituted acetylenes by MoCl5- and MoOCl4-based catalysts
Abstract
New catalyst systems composed of MoCl5(or MoOCl4), Bun4Sn, and-ethanol (molar ratio 1:1:0.5) effect living polymerisations of 1-chloro-oct-1-yne and o-(trimethylsilyl)phenylethyne, which are the first examples of living polymerisation of acetylenes.
