英文摘要	The development of organometallic single-site catalysts (SSCs) has inspired the designs of new heterogeneous catalysts with high efficiency. Nevertheless, the application of SSCs in certain modem organic reactions, such as C-C bond formation reactions, has still been less investigated. In this study, a single-site Pd(II) catalyst was developed, where 2,2'-bipyridine-grafted periodic mesoporous organosilica (PMO) was employed as the support of a Pd(II) complex. The overall performance of the single-site Pd(II) catalyst in the oxidative Heck reaction was then investigated. The investigation results show that the catalyst displays over 99% selectivity for the product formation with high reaction yield. Kinetic profiles further confirm its high catalytic efficiency, showing that the rate constant is nearly 40 times higher than that for the free Pd(II) salt. X-ray absorption spectroscopy reveals that the catalyst has remarkable lifetime and recyclability.; National Research Foundation (NRF); Prime Minister's Office, Singapore, under its NRF Fellowship [NRF2009NRF-RF001-015]; Campus for Research Excellence and Technological Enterprise (CREATE) Programme Singapore Peking University Research Centre for a Sustainable Low-Carbon Future; NTU-A*Star Silicon Technologies Centre of Excellence [112 351 0003]; U.S. Department of Energy, Office of Science, and Office of Basic Energy Sciences [DE-AC02-06CH11357]; U.S. Department of Energy; MRCAT; SCI(E); EI; ARTICLE; aiwenlei@whu.edu.cn; zhaoyanli@ntu.edu.sg; 6; 3752-3759; 5
