Abstract: The invention relates to a process for the preparation of the trans-isomer of an alkenyloxy compound of the formula (I> CH3-(CH2)m-CH = CH-(CH2)n.OR in which m and n in each case represent an integer from 1 to 10 and R represents a hydrogen atom, an aliphatic C1- to C4-acyl radical, a trialkylsilyl radical or a tetrahydropyranyl radical, from the cis-isomer by rearrangement/isomerisation by means of short-wave light in the presence of a disulphide compound as sensitiser.

Abstract: A process for the production of beta -alkoxy-nitriles which is carried out in the presence of a basic diazabicycloalkene catalyst. Production of beta -alkoxy-nitriles which involves reaction of alpha , beta -unsaturated nitriles with mono-, di- or tri- valent alcohols in the presence of a basic diazabicycloalkene of formula (1), at (-) 20-200 degrees C. n, m = 1-6; and where the 1-4 H atoms are optionally substituted by R -R ; R -R = 1-20C alkyl, 6-20C aryl or 7-20C arylalkyl. An Independent claim is also included for a production process of a gamma -alkoxy-amine by hydrogenation of the beta -alkoxy-nitrile in the presence of a hydrogenation catalyst and the catalyst of formula (1).
