Aqueous/organic biphasic hydroformylation of 4-isobutylstyrene (IBS) cataly
zed by OPGPP/Rh catalyst which possesses the function of 'thermoregulated p
hase-transfer catalysis' (TRPTC) was investigated. A high IBS conversion of
99.5% and an aldehyde yield of 99.0% were obtained under the condition of
80 degrees C and 4.0 Mpa. The molar ratio of branched/normal (b/n) aldehyde
in the product reaches 2.5. (C) 1999 Elsevier Science B.V. All rights rese
