selected transition metals has been studied. The syntheses and spectroscopic properties of polydentate bis(5-t-butyl-[1,2,3]-diazaphosphol-2-yl)-dimethylsilane (BdapsH,tBu) and bis(4-methyl-5-ethyl-[1,2,3]-diazaphosphol-2-yl)-dimethylsilane (BdapsMe,Et) are reported. In zerovalent compounds of the type [M(CO)4(κ2-P,P′-BdapsR1,R2)] (R1 = Me, R2 = Et, M = Cr, Mo and W; R1 = H, R2 = t-Bu, M = W) and [Ni(κ2-P
制备了基于[1,2,3]-二氮杂磷(dap)的新型杂化配体,并研究了它们对所选过渡金属的配位行为。多齿双(5-叔丁基-[[1,2,3]-二氮杂磷-2-基)-二甲基硅烷(Bdaps H,t Bu)和双(4-甲基-5-乙基-[报道了1,2,3]-二氮杂磷-2-基)-二甲基硅烷(Bdaps Me,Et)。在所述类型的零价化合物[M(CO)4(κ 2 - P,P ' - Bdaps R1,R2)](R1 = Me中,R2 =的Et,M = Cr,Mo和瓦; R1 = H,R2 =吨-Bu,M = W)和[镍(κ 2 -P,P ' - Bdaps H,吨卜)2 ]配体用作P,P '端供体,使刚性六元螯合环。Bdaps ME等也能够表现为一个的Ñ,Ñ '-chelator由高自旋螯合络合物的隔离所证实[COBR 2(κ 2 - Ñ,ñ ' - Bdaps ME等)]。母体2 H -4-甲基-5-乙基-[1
