空气和水稳定的乙炔配合物[Mu-BNMe(2)({eta(5)-C(5)H(4)Me)Mn(CO)(2)}(2)](1a)与Et(2)O中的HCl溶液反应得到相应的氯丁烯络合物[mu-Chloroborylenebis(dicarbonyl(eta(5)-methylcyclopentadienyl)manganese)(Mn-Mn)](2)，该化合物很容易与伯胺、醇和水等质子剂在金属配位的乙炔部分进行进一步的取代反应，给出了[Mu-BX{(ETA(5)-C(5)H(4)Me)Mn(CO)(2)}(2)](3a，b：X=NHtBu，NHPh；4a，b：x=OMe，OEt；5：X=OH)。用多核核磁共振法和红外光谱对所有化合物进行了表征，并用单晶X-射线衍射法确定了4b的晶体结构。
The reaction of the air-and water-stable borylene complex [mu-BNMe(2)({eta(5)-C(5)H(4)Me)Mn(CO)(2)}(2)] (1a) with a solution of HCl in Et(2)O affords the corresponding chloroborylene complex [mu-Chloroborylenebis(dicarbonyl(eta(5)-methylcyclopentadienyl)manganese)(Mn-Mn)] (2), This compound easily undergoes further substitution reactions with protic reagents such as primary amines, alcohols and water at the metal coordinated borylene moiety with elimination of HCl, giving new products of the type [mu-BX{(eta(5)-C(5)H(4)Me)Mn(CO)(2)}(2)] (3a, b: X = NHtBu, NHPh; 4a, b: X = OMe, OEt; 5: X = OH). All borylene complexes were isolated as crystalline solids in good yields and characterized by multinuclear NMR methods and IR spectroscopy in solution, In addition, the structure of 4b in the crystalline state was determined by a single-crystal X-ray study.
