10. Although supported ionic liquid catalysis has been investigated recently, there has been no example of combination of silica-supported metal catalysts with ionic liquids before our recent report (ref 3). In the supported ionic liquid catalysis, it is reported that silica gel-supported ionic liquids and additional nonsupported ionic liquids form ionic liquid phases on the surface of silica gel due to interactions between supported and nonsupported ionic liquids. For supported ionic liquid catalysis see: (a) Mehnert, C. P.; Cook, R. A.; Dispenziere, N. C.; Afeworki, M. J. Am. Chem. Soc. 2002, 124, 12932.
