Abstract

Mnlv(saIpn)Cl2 regioselectively trans-halogenates alkenes in a reaction for which the Mn-containing product is also identified; this is the first Mn-based halogenating system for which the reactive and final Mn-containing products a re structu ra I ly characterized. ... Several reagents exploiting moderate or high valent manganese are known that trans-chlorinate alkenes. These include MnIV02-Me3SiC1 in THF (40-60 oC)1-2 and MnlI1 acetate- CaC12 (5 : 6)3 or MnIII ...
