Application of palladium (trioxo-adamantyl cage phosphine)chloride complexes as catalysts for the alkoxycarbonylation of styrene; Pd catalysed tert-butoxycarbonylation of styrene

Pre-catalysts of type where the monophosphine is one of the tri-oxo-adamantyl cage phosphines such as 1,3,5,7-tetramethyl-6-phenyl-2,4,8-trioxo-6-phospha-adamantane give very high reactivity in the regioselective hydroxycarbonylation and alkoxycarbonylation of styrene at 60 °C. This high reactivity enables the use of tert-butanol as nucleophile in the alkoxycarbonylation of styrene
