摘要：

The mechanism of hydrogen transfer from indoline to cycloheptene in toluene catalyzed by RhCl(PPh 3) 3 has been studied. The rate data of the reaction can be accommodated by the rate expression of the form, rate = a[D][C] 0/(b + [L]) where [C] 0, [D], and [L] are the concentration of the catalyst, indoline, and triphenylphosphine, respectively. The rate-determining step of the reaction is inferred to be the dehydrogenation of indoline, that is, the hydrogen transfer from the amine to a Rh(I) complex to form a hydride complex by oxidative addition.
