The effect of the structure of substrates and reaction conditions on the preparation of acetylene-1,4-diols. I. One-stage syntheses. Olejnik, Marian; Jasiobedzki, Wieslaw (Instrum. Anal. Lab., Tech. Univ. Warsaw, Warsaw 00-664, Pol.). Bull. Pol. Acad. Sci., Chem. 2700-47-2 and 106149-65-9 which are cas registry numbers of chemicals are mentioned., Volume Date 1985, 33(11-12), 459-65, 1 plate (English) 1986. CODEN: BPACEQ. DOCUMENT TYPE: Journal CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) RR1C(OH)CYCC(OH)RR1 (R = 2-pyridyl, 2-naphthyl, 6-methoxy-2-naphthyl, 9-phenanthryl, 4-R2C6H4, R2 = MeO, Cl, MeS, R1 = Et; R = Ph, R1 = Me2CHCH2, Me3CCH2) were prepd. by the reaction of BrMgCYCMgBr with RR1CO. When R = 9-anthracyl, 1-naphthyl, 2,4,6-Me3C6H2, 4-R2C6H4 (R2 = O2N, Me2N, MeSO2) the initial ketone was recovered. .
