Abstract
1-Formyl-2,6,6-trimethyl-cyclohex-1-ene derivatives of the formula I ##STR1## where R is --H or --CH.sub.3 and A is O or NOH are prepared by nitrosylating the corresponding 1-formyl-2,6,6-trimethyl-cyclohex-1-ene or -cyclohex-2-ene and, where appropriate, hydrolyzing the resulting oxime (where A is NOH) to the corresponding ketone (where A is O). The compounds I, except where R is H and A is O, are novel.
