| titleOfInvention | Process for the preparation of 2-benzoxazolones |
| abstract | A B S T R A C T The invention relates to a process for the preparation of a 2-bezoxazolone of the formula (I) wherein X represents a halogen atom, an alkyl group of from one to ten carbon atoms or a group OR in which R represents an alkyl group of from one to ten carbon atoms, a cyano group or a trifluoromethyl group, and n is from 0 to 4, which comprises reacting an ortho-nitro-phenol of the formula (II) wherein X and n are as defined above, with carbon monoxide in the presence of a catalytic system comprising a) palladium and/or a palladium compound b) a ligand having the formula III (III) in which Z and Y represent the same or different bridging groups each of which has 3 or 4 atoms in the bridge, of which atoms at least two are carbon atoms and which groups Z and Y may be bound to each other by means of a connection other than that already formed by the carbon atoms shown in formula III and c) an anion of an acid having a pK of less than 2, except of a hydrohalogenic acid. |
