Improved synthetic routes to molybdenum-nitrido compounds

摘要

Convenient synthetix routes to the compoundsMoBr4, MoNBr3, and MoNBr2(bpy) are described using Mo(CO)6,Br2, (CH3)3SiN3, and 2, 2'-bipyridine as inexpensive and readilyavailable starting materials. These one-pot syntheses produceanalytically pure compounds in multigram quantities with highyields under mild conditions. Use of (CH3)3SiN3 as a nitridesource is preferable to that of unstable and explosive IN3 whichhas been utilized in a previous synthesis of MoNBr3-
