Abstract

Abstract Copper (I) complexes of approximate composition (CuCN) 4·(DMF) 2· RR′ C (OH) C CBr have been isolated from copper (I) cyanide and 1-bromopropyn-3-ols in dry dimethylformamide (DMF). Decomposition of thes complexes with aqueous DMF gives 4- hydroxybutynenitriles in about 60% yield. For preparative purposes it is not necessary to isolate the complex, similar yields being obtained in a one step process. Decomposition of ...
