A series of - and -substituted -carborane derivatives with a pendant pyridyl group was prepared. The synthesized compounds were used as ligands in the complexation reactions with bis(triphenylphosphine)nickel(II) and palladium(II) chlorides to give six new metallacomplexes with unusual η:κ()-coordination of the metal center. The single crystal structures of 1-(NCH-2'-S)-1,2-CBH, 1-(NCH-2'-CHS)-1,2-CBH, Cs [7-(NCH-2'-CHS)-7,8-CBH] - and -carboranes and 3-PhP-3-(4(7)-NCH-2'-S)--3,1,2-NiCBH and 3-PhP-3-(4(7)-NCH-2'-CHS)--3,1,2-NiCBH metallacarboranes were determined using single crystal X-ray diffraction.
一系列带有吡啶侧基的 - 和 - 取代的卡硼烷衍生物被制备出来。所合成的化合物被用作与双（三苯基膦）镍(II)和钯(II)氯化物的配合反应中的配体，得到六个具有金属中心异常的 η:κ()-配位的新型金属配合物。1-(NCH-2'-S)-1,2-CBH、1-(NCH-2'-CHS)-1,2-CBH、Cs [7-(NCH-2'-CHS)-7,8-CBH] - 和 - 卡硼烷以及 3-PhP-3-(4(7)-NCH-2'-S)--3,1,2-NiCBH 和 3-PhP-3-(4(7)-NCH-2'-CHS)--3,1,2-NiCBH 金属卡硼烷的单晶结构通过单晶 X 射线衍射确定。
