Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of Organometallic Chemistry called Synthesis of a tris(pyrazolyl)borate-stabilized molybdenum alkylidene and its hydrolysis products. Crystal structures of TpMo(CH2C(Me)2Ph)(NAr)(O) and [TpMo(NAr)(O)]2O, Author is Vaughan, William M.; Abboud, Khalil A.; Boncella, James M., which mentions a compound: 18583-60-3, SMILESS is [BH-](N1N=CC=C1)(N2N=CC=C2)N3N=CC=C3.[K+], Molecular C9H10BKN6, Name: Potassiumtris(1-pyrazolyl)borohydride.
The synthesis of a tris(pyrazolyl)borate-stabilized molybdenum(VI) imido alkylidene complex, TpMo(CHC(Me)2Ph)(NAr)(OTf) (1) [Ar = 2,6-i-Pr2-C6H3, Ph = C6H5, OTf = OSO2CF3], has been achieved by addition of potassium hydridotris(1-pyrazolyl)borate (KTp) to Mo(CHC(CH3)2Ph)(NAr)(OTf)2(DME). Stirring compound 1 over alumina in the presence of H2O gave TpMo(CH2C(Me)2Ph)(NAr)(O) (2). Alternatively, compound 1 was converted to 2 by the addition of CsOH·H2O in THF. A single crystal of [TpMo(NAr)(O)]2O (4) was isolated from a solution of 2. Compounds 2 and 4 have been characterized by x-ray crystallog. and the bonding considerations about the molybdenum atoms are discussed.
