Polyazolyl chelate chemistry. IV. Dihydrobis(benzotriazolyl)borato complexes of ruthenium(II)

Abstract

The reactions of the salt K[H2B(bta)2] (bta = benzotriazol-1-yl) with the compounds [RuCIR(CO)-(PPh3)n] (n = 3, R = H; n = 2, R = C6H4Me-4, CHCHC6H4Me-4, CHCHC4H9, C(CCHPh) give high yields of the chelate complexes [RuR(CO)(PPh3)2{η2-H2B(bta)2}]. The hydrido complex can also be made by similar treatment of the salt [RuH(NCMe)2(CO)(PPh3)2]BF4, and gives the chloro-derivative [RuCl(CO)(PPh3)2{η2-H2B(bta)2}] upon treatment with N-chlorosuccinimide.
