The complex [MnCl3(OPPh3)(2)] (1) is a bench-stable source of MnCl3 that can be used in coordination reactions and alkene dichlorinations in various solvents.
The complex [MnCl3(OPPh3)(2)] (1) is a bench-stable and easily prepared source of MnCl3. It is prepared by treating acetonitrile solvated MnCl3 (2) with Ph3PO and collecting the resulting blue precipitate. 1 is useful in coordination reactions by virtue of the labile Ph3PO ligands, and this is demonstrated through the synthesis of {Tpm*}MnCl3 (3). In addition, methodologies in synthesis that rely on difficult or cumbersome to prepare solutions of reactive MnCl3 can be accomplished using 1 instead. This is demonstrated through alkene dichlorinations in a wide range of solvents, open to air, and with good substrate scope. Light accelerated halogenation and radical sensitive experiments support a radical mechanism involving stepwise Cl-atom transfer(s) from 1.
