摘要:
Process for the production of cycloalkanecarboxylic acids of general Formula I ##STR1## wherein n means the number 1 or 2,R.sub.1 and R.sub.3 are alkyl groups of 1-4 carbon atoms, andR.sub.2 and R.sub.4 symbolize hydrogen atoms or alkyl groups of 1-4 carbon atoms,characterized by reacting a compound of general Formula IIX--CR.sub.1 R.sub.2 --(CH.sub.2).sub.n --CH.sub.2 --CR.sub.3 R.sub.4 --X'(II),whereinn, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 have the meanings given above andX and X' mean a hydroxy group, a chlorine atom, a bromine atom, an alkylsulfonyloxy residue, or an arylsulfonyloxy residue,with 1,1-dichloroethylene;splitting off hydrogen chloride from the thus-obtained compounds of general Formula IIIX--CR.sub.1 R.sub.2 --(CH.sub.2).sub.n --CH.sub.2 --CR.sub.3 R.sub.4 --CH.sub.2 --CCl.sub.2 X (III),wherein n, X, X', R.sub.1, R.sub.2, R.sub.3 and R.sub.4 have the meanings given above; and cyclizing and hydrolyzing, by means of acids, the thus-prepared compounds of general Formula IVX--CR.sub.1 R.sub.2 --(CH.sub.2).sub.n --CH.sub.2 --CR.sub.3 R.sub.4 --CY.dbd.CZX' (IV),whereinn, X, X', R.sub.1, R.sub.2, R.sub.3 and R.sub.4 have the meanings given above, andY and Z jointly represent a carbon-to-carbon bond or mean a hydrogen atom and a chlorine atom.
