The reduction of MoCl 5 with metallic tin in diethyl ether provides a rapid and convenient entry to [MoCl 4 (OEt 2 ) 2 ] This compound can be transformed easily and in high yields into a variety of other useful synthons. The loss of ether in the solid state affords a new and reactive form of MoCl 4 . Treatment with THF, PMe 3 or LiO t Bu affords [MoCl 4 (THF) 2 ], [MoCl 4 (PMe 3 ) 3 ] or [Mo(O t Bu) 4 ] in high isolated yields. Treatment with metallic tin in THF affords [MoCl 3 (THF) 3 ] All of these reactions can be carried out under simple experimental conditions and represent significant improvements relative to previously reported syntheses of the same compounds.
