X. Li, H. Wu, W. Xiao, R. N. Lett-chapman, P. S. Arora et al., For microwave-assisted CM, see As the CM is a reversible process, the TON (turnover number) represents the average number of substrate molecules converted into the cross-product per molecule of catalyst . A typical loading of 1a,b in CM reaction is 2-10%, which correspond to a maximum TON of 10-50.
