The syntheses of high-yield carbon-rich materials as acetylenic precursors, in general, have received much attention [7].
Here we see comprehensive coverage of the cotrimerizations of acetylenic compounds and glycosylation on polymer supports along with a very helpful list of cumulative chapter titles by volume.
Acetylenic diols are nonionic, so this mechanism does not apply.
