A homologous series of alkynyl chalcoether complexes: [W( η 2 - i PrEC CPh)(CO) 2 (Tp*)]BF 4 (E = O, S, Se, Te; Tp* = hydrotris(dimethylpyrazol-1-yl)borate)

structurally characterized salts [W(η2-iPrECCPh)(CO)2(Tp*)]BF4 (A = O, S, Se, Te; Tp* = hydrotris(dimethylpyrazolyl)borate), result from the reactions of the free alkynes iPrECCPh with [WI(CO)3(Tp*)] in the presence of AgBF4. The neutral complex [W(η2-iPrSeCCPh)Cl(CO)(Tp*)] is obtained from the reaction of [W(η2-iPrSeCCPh)(CO)2(Tp*)]BF4 with [nBu4N]Cl and co-exists in two forms in solution as a result

The complexes TpWO2X react with sulfiding agents such as B2S3 or P4S10 to give the oxothio- and bis(thio)tungsten(VI) complexes TpWOSX (X = Cl(-)) and TpWS2X [X = Cl(-), S2PPh2(-); Tp = hydrotris(3,5-dimethylpyrazol-1-yl)borate]. The reaction of TpWS2Cl with (i) PPh3 in pyridine and (ii) dimethyl sulfoxide affords TpWOSCl in good overall yield. The chloro complexes undergo metathesis with alkali metal

New molybdenum(0), molybdenum(II), manganese(I), rhenium(I), silver(I), and copper(I) complexes with the 1,3,5-tris(thiocyanatomethyl)mesitylene [Ms(CH2SCN)3] ligand have been synthesized and characterized by IR, NMR, and by X-ray diffraction (except for the rheniumcomplex). The Ms(CH2SCN)3 ligand coordinated with the molybdenum, manganese, and rheniumcarbonyl fragments as a tripodal chelate. With
