The tandem isomerization and nucleophilic aromatic substitution of allylic fluoro‐substituted benzylic alcohols is described for the first time. In the presence of the ruthenium complex Ru(PPh3)3(CO)(H)2, 1‐(4‐fluorophenyl)prop‐2‐en‐1‐ol is converted into the corresponding para‐amino ketone or para‐phenolic substituted ketone.

A novel process for the preparation of compounds of formula I ##STR1## by aminolysis of a p-halophenyl alkyl ketone of formula II ##STR2## with a cyclic amine of formula III ##STR3## in water at a temperature of at least 130.degree. C., in which formulae X is a halogen atom and R.sub.1, R.sub.2 and R.sub.3 are as claimed in claim 1, as well as the novel compounds of formula I and their use for the preparation of photoinitiators for the photopolymerisation of ethylenically unsaturated compounds.
The invention relates to a curable thiol-ene composition comprising either compound A and compound B, or a compound B further comprising polythiol functionality as defined under (A), wherein (A) a polythiol, (B) a compound having a plurality of cyclic ene groups thereon, wherein said compound (B) comprises a carbonyl group directly attached to at least one cyclic ene group and comprises at least one hydrogen donating group, wherein the distance between at least one of said cyclic ene groups and at least one of said hydrogen donating groups is at least two skeletal bonds, wherein compound (B) does not contain a (meth)acrylate group, and 0-10 wt. % of a (free-radical) photoinitiator. The invention further relates to the use of such composition fiber optical coating, stereolithography resin, medical coating and adhesive.
