We shall only discuss the on shell scheme (Sirlin, 1980) in which (7.2.6) holds exactly. To emphasize this we shall use the symbols s and where, by definition,... 

Some rhodium catalysts for hydroformylation of epoxides have been claimed by Union Carbide and Shell (Scheme 6.106) [17]. By the use of phosphites (e.g., Alkanox 240, BIPHEPHOS) or phosphine-modified rhodium catalysts, the selectivity was enhanced and the reaction temperature could be lowered. Noteworthy, occasionally a higher partial pressure of Hg in the syngas mixture with a total pressure of 90 bar was employed.

In a similar procedure, Binder et al. used a TIPNO-based alkoxyamine bearing a 1,2-diol function for its attachment onto iron oxide. This system was used for the preparation of core-shell Fe203 nanoparticles with a well-defined PNIPAM shell (Scheme 12) [41]. The polymerization reaction was performed in V,V-dimethyl-formamide (DMF) at 150°C. Under these conditions, monomer conversion reached 90% and experimental M was 5,600 g mol Poly (4-vinylpyridine) (P4VP) brushes were prepared by SI-NMP on the surface of...
