Reaction of the tris(carbene)borate ligand PhB(MeIm)3- with [Mn(CO)3(tBuCN)Br]2 leads to the manganese(I) tricarbonyl complex PhB(MeIm)3Mn(CO)3. In contrast to related complexes that are air-stable, PhB(MeIm)3Mn(CO)3 is O2-sensitive and is converted to a homoleptic MnIV complex. IR and cyclic voltammetry measurements of these complexes establish the exceptionally strong donating nature of the tris(carbene)borate ligand.
三（卡宾）硼酸酯配体PhB(MeIm)₃⁻ 与[Mn(CO)₃(tBuCN)Br]₂反应生成锰（I）三羰基配合物PhB(MeIm)₃Mn(CO)₃。与空气稳定的相关配合物不同，PhB(MeIm)₃Mn(CO)₃对O₂敏感，并转化为同配体MnIV配合物。这些配合物的红外光谱和循环伏安测量确定了三（卡宾）硼酸酯配体具有异常强的给电子性质。
