addition of CCl 4 to internal olefins. The activity of Cp ∗ Ru(PTA)(PPh 3 )Cl and Cp ∗ Ru(PTA)(PMe 3 )Cl were comparable to that of the highly efficient ATRA catalyst, Cp ∗ Ru(PPh 3 ) 2 Cl. The addition of CCl 3 CO 2 Et to styrene catalyzed by Cp′Ru(PPh 3 )(PR 3 )Cl (Cp′ = Dp, Ind, Cp, Tp) are also reported here. Two new compounds, 3-chloro-3-phenyl-2-(trichloromethyl)-1-phenylpropan-1-one and 1,3,3,3-tetrachloro-1
使用Cp ∗ Ru(PPh 3)(PR 3)Cl络合物,其中PR 3 = PMe 3,PPh 3或
PTA(
PTA = 1,3,5-triaza-7-phosphaadamantanetan)催化原子转移自由基向
苯乙烯中添加
氯化酯(CCl 3 CO 2 Et,CH 2 ClCO 2 Et),以及向各种烯烃添加CCl 4。单加合物以中等至优异的产率获得。此外,获得高选择性以将CCl 4加到内烯烃中。Cp * Ru(
PTA)(PPh 3)Cl和Cp * Ru(
PTA)(PMe 3)Cl的活性与高效A
TRA催化剂Cp * Ru(PPh 3)2 Cl的活性相当。在此还报道了通过Cp'Ru(PPh 3)(PR 3)Cl(Cp'= Dp,Ind,Cp,Tp)催化将CCl 3 CO 2 Et加到
苯乙烯中。两种新化合物3-
