| abstract | Cpds. of formula (in which R is H, or an aliphatic, cycloaliphatic or aromatic hydrocarbon radical, opt. contg. halogens, NO2, and/or alkoxy gps) are produced by reacting 3-methylbut-3-en-1-ol or 3-methylbut-2-en-1-ol with RCN in the presence of an acid condensation agent (pref. conc. H2SO4 or H3PO4) good yields are obtained. These cpds. are used in chain-extending reactions, esp. for aldehydes, ketones and acids by 2 or 3C atoms. |
