Supported hydrogenation

Bromofluorination of double bonds using polymer-supported hydrogen fluoride-jV-bromosuccinimide (NBS) or BU4NF-NBS (Ref. 330) has been reported. [Pg.177]

An alternative to the supported liquid phase (SLP) method was recently proposed using the same type of solid the supported hydrogen bonded (SHB) catalysts. First demonstrated with the zwitteronic Rh1 catalysts [(sulphos)Rh(cod)] (1) and [(sulphos)Rh(CO)2] (2) (sulphos = 03S(Cr,I I4)CI I2C(CH2PPh2) ). the immobilization procedure is based on the capability of the sulfonate tail of sulphos to link the silanol groups of the support via hydrogen bonds (Figure 12). [Pg.456]

For this reason, these catalysts are also known under the name of supported hydrogen-bonded (SHB) catalysts and, in conjunction with Pd° particles on the same support material, have contributed to generate active heterogeneous systems for the hydrogenation of benzenes in aprotic solvents. Irrespective of the substrate, the combined single-site/dispersed-metal catalyst RhI-Pd0/SiO2 shown in Figure 16.5a was from four- to six-fold more active than supported palladium... [Pg.467]
