Abstract

The 'Teflon greaseball' [RhCl{P[CH2CH2(CF2)5CF3]3}3] (1) is highly soluble in CF3C6F11 and catalyzes a variety of organic transformations. The products can be extracted with organic solvents, and the solution of 1 reused. This environmentally friendly protocol is showcased for hydroboration, in which the customary oxidative workup destroys the metal catalyst. Catalyst loadings of only 0.01-0.25 mol% are effective under mild conditions (25-40 °C, 1-40 h) and give turnover numbers as high as 8500.
