Although the mechanistic details are not clear, previous experiments by McNulty and coworkers [9,10] showed that silver acetylide
formation plays an important role in the catalytic cycle as well as other intermediates .
Sadoway, MIT, carried out exploratory studies into the technological feasibility of the synthesis of diamond-like carbon films from solution (as opposed to the fairly well developed technology used for chemical vapour deposition) by electrochemical oxidation of acetylene and acetylides
. As they reported in the symposium "Electrochemistry at the Edge," thin carbon films were successfully deposited by this method and thicker conducting films could be grown by addition of boron to produce a p-doped semiconductor.
Writing for professionals, the authors cover theoretical studies on acetylenic scaffolds, synthesis of heterocycles and carbocycles by electrophilic cyclization of alkynes, addition of terminal acetylides
to CO and CN electrophiles, transition metal acetylides
, acetylenosaccharides, semiconducting poly(arylene ethylene)s, polyynes via alkylidene carbenes and carbenoids, macrocycles based on phenylacetylene scaffolding, carbon-rich compounds, shape-persistent acetylenic macrocycles for ordered systems, and chiral acetylenic macromolecules.
