The regioselectivity of catalysts generated in situ from dicarbonyl rhodium(I)(2,4-pentanedione) and trifluoromethyl-substituted triphenylphosphine ligands has been evaluated during the hydroformylation of 1-octene. The influence of batch or semi-bat

Inexpensive Al 2 O 3 can be used as a simple catalyst for alkene epoxidation, using anhydrous hydrogen peroxide as oxidant. This system is active and selective in the epoxidation of several alkenes. Besides the epoxidation of the terpenes limonene an

Perrhenic acid in combination with tertiary arsines gives a versatile catalytic system for epoxidation of alkenes with hydrogen peroxide. The best results are obtained with diphenylmethylarsine. A wide range of alkenes could be epoxidised with aqueou

Tertiary arsines are active and selective catalysts for the epoxidation of a variety of alkenes with hydrogen peroxide at low catalyst loading (1–5 mol%); highly fluorinated analogues of these arsines can be recovered and reused with moderate effic
