CYANOALKYNES VIA IODIDE-CATALYZED CYANATION OF TERMINAL ACETYLENES WITH CUPROUS CYANIDE IN THE PRESENCE OF TMSCI AND H20 IN DMSO/CH3CN9... [Pg.76]

The preparation of alkyl, alkenyl, and aryl derivatives of cyanoacetylene (1) poses no particular problems. In most cases a terminal acetylene is metalated or converted into an alkynyl Grignard reagent, and these intermediates are subsequently intercepted by a cyano source , which in most cases is either cyanogen chloride or bromide and sometimes cuprous cyanide or phenyl cyanate. Of course, dehydration of an acetylenic amide as described for the parent molecules is also possible and has occasionally been employed. [Pg.36]
