Amine-Assisted C−Cl Bond Activation of Aryl Chlorides by a (Phebox)Rh-Chloro Complex
摘要:
Oxidative addition of chlorobenzene and p-chlorotoluene by (Phebox)RhCl2(H2O) (1) in the presence of diisopropylamine was examined and was shown to produce the corresponding aryl complexes (Phebox)RhCl(Ar)(H2O) in high yields via C-Cl bond cleavage. Reaction of 1 with chloropyridine in the presence of diisopropylamine provided a pyridinium rhodate complex.
Carbon−Carbon Bond Formation on a Bis(oxazolinyl)phenyl−Rhodium Complex in a Reduction and Oxidative Addition Sequence
摘要:
The unique C-C bond formation reaction between diisopropylamine and CH2Cl2 proceeding on a bis(oxazolinyl)phenyl rhodium complex (tBu-Phebox-dm)RhCl2(H2O) (1) was discovered. The intermediary chloromethyl complex, (tBu-Phebox- dm)Rh(CH2Cl)Cl(NEt3), which was obtained by reaction of 1 with CH2Cl2 in the presence of amine, underwent C-C bond formation with imine to give an azarhodacyclopentene complex, 2.
