Silica Foams Si- HIPE

Pd gAmino-Si-(HIPE), in this case 0.055 g of support was used instead of the 0.11 g used for all the other tests. Conversion yields are the average of two GPC analyses. (Adapted with permission of American Chemical Society, Copyright 2008.) 

3 Pd Organo-Si-(HIPE) Cycling Heck Catalysis Reactions 

To investigate the influence of Pd loading, the Pd/iodobenzene molar ratio was set at 0.002 or 0.004. Corresponding TON and TOF are reported in Table 3.1. The values obtained are reaching the best results for silica-based supports considering the work fi-om Crudden et al. [113]. 

Compared with other enzyme-based heterogeneous catalysts [43,120-122], this one has high esterification catalytic performances, associated with higher stability in time. Whatever the supports used in literature [40-43], the conversions are
