Abstract

It is investigated whether the catalyst system Ag‐In/SiO~2~ can be applied in the selective hydrogenation of citral, with the aim of synthesizing the acyclic, allylic terpene alcohols geraniol/nerol with high selectivity and space‐time yield. In addition, as liquid‐phase hydrogenations are often also influenced by the choice of solvent, it is of interest to know how the solvent, in particular in terms of its polarity and hydrogen solubility, affects the activity and the selectivity of catalysts during hydrogenation of the Ξ±,β‐unsaturated aldehyde citral.

The molybdenum(VI)-catalysed oxybromination of ethynylbenzene was performed with hydrogen peroxide as oxidant and potassium bromide as source of bromine, in a two-phase water/solvent system, where solvent was either dichloromethane or an ionic liquid. The selectivity was toward 1,2-dibromostyrene wh
