Pd-catalyzed cross-coupling of alkynylsilanols with iodobenzenes
摘要:
Alkynylsilanols were efficiently coupled with iodobenzene derivatives by a Pd catalyst ill the presence of TBAF, and the corresponding substituted alkynes could be obtained in good to excellent yields. (C) 2001 Elsevier Science Ltd. All rights reserved.
[GRAPHICS]A heterogeneous ruthenium catalyst, easily prepared by adsorption of [RuCl2(p-cymene)](2) on activated carbon, exhibited a highly efficient and selective catalytic activity in various environmentally attractive transformations such as aerobic oxidation, hydrolytic oxidation, and dehydration processes with excellent recyclability.
