palladium(II) and platinum(II) halides affords cis-[M(B5H8)(PR3)2X] in good yields (X = Cl, Br, I, or Me; PR3= PPh3, PMe2Ph, PMe3, or ½Ph2PCH2CH2PPh2). The platinum complexes are more stable than those of pailadium and can be stored unchanged for long periods at room temperature. Similar reactions with appropriate starting materials lead to cis-[Pt(B5H8)Cl(AsPh3)2], cis-[Pt(B5H8)(PMe2Ph)(µ-SMe)}2], and the
碘化-八氢五硼酸钾K [B 5 H 8 ]与钯(II)和卤化铂(II)的许多顺式-双(膦)配合物复分解得到顺式-[M(B 5 H 8)(PR 3)2 X]以良好的收率(X =氯,溴,I,或Me; PR 3 = PPH 3,PME 2 PH,PME 3,或½Ph 2 PCH 2 CH 2 PPH 2)。铂配合物比钯配合物更稳定,并且可以在室温下长时间不变地保存。使用适当的原料进行的类似反应会生成顺式[[Pt(B 5 H 8)Cl(AsPh 3)2 ],顺式[[Pt(B 5 H 8)(PMe 2 Ph)(µ-SMe)} 2 ]。 ,以及不太稳定的反式-[Pt(B 5 H 8)I(PMe 2 Ph)2 ]和反式-[Pt(B 5 H 8)Me(PMe 2 Ph)2]。在所有情况下,乙5 ħ 8配体为η 2键合的与金属经由两个基底硼原子B(2)和B(3)的。氢-1,11 B,31 P,和195的Pt
