Assembled Monolayers of Metal Complexes on Single-Crystal Surfaces 

The amounts of Rh and P were also estimated by XPS, indicating the formation of a 1 1 Rh P complex on the Au surface. The surface density of the Rh complex was estimated to be 0.63 nmolcm by inductively coupled plasma mass spectrometry (ICP-MS). 

The platelike shape of the [Au]-SMAP-Rh (C) chip enables easy separation of the catalyst and reaction mixture. Indeed the catalyst can be recycled by physically transferring the used catalyst chip into another reaction vessel. The second use of [Au]-SMAP-Rh (C) resulted in a similar performance (TON of 61000 for 16h), demonstrating that catalytic activity was maintained. In the fourth run, a slight decrease in TON was observed (Table 7.1), but the superior recyclability of supported [Au]-SMAP-Rh (C) versus the homogeneous systems was evident. Leaching of the Rh complex was lesser than 0.5%. 

Reaction-Induced and Photoinduced Formation of Unsaturated Ru Complexes Supported on SiOj Surfaces 

A metal complex catalyst often releases its Hgand into a homogeneous reaction solution to form the catalytically active species during the initial stage of the catalytic cycle. However, the stability of such activated species is usually low, and
