methodologies were developed for the preparation of half-sandwich osmium complexes with the general formula (η5-cyclopentadienyl)OsCl(PPh3)2. The first approach involves the reactions of OsH3Cl(PPh3)3 with cyclopentadienes. Treatment of OsH3Cl(PPh3)3 with cyclopentadienes gives (η5-cyclopentadienyl)OsCl(PPh3)2 via C−H oxidative addition of cyclopentadienes followed by reductive elimination of hydrogen. The
两种方法被用于制备半夹心络合物锇与通式显影(η 5 -环戊二烯基)OSCL(PPH 3)2。第一种方法涉及OsH 3 Cl(PPh 3)3与环戊二烯的反应。职业安全与卫生的治疗3氯(PPH 3)3与环戊二烯,得到(η 5 -环戊二烯基)OSCL(PPH 3)2通过C-H氧化加成环戊二烯,随后还原消除氢。该方法使我们能够合成一系列包含Cp,Cp *,茚基和C的半三明治络合物5 Me 4 R(R = H,Et,n -Pr)。第二种方法涉及OsH 3 Cl(PPh 3)3与富烯的插入反应。职业安全与卫生的治疗3氯(PPH 3)3与C 6 -C取代的富烯产生干净地单取代的环戊二烯基配合物锇(η 5 -C 5 H ^ 4 CHRR')OSCL(PPH 3)2(R = H,R'= p -C 6 H 4 CH 3,p -C 6 H 4 OCH 3,CMe 3 ; R = R'= Ph)通过氢化物转移到富

)−H Amidation
Benzofused lactams, especially indolin‐2‐one and dihydroquinolin‐2‐one are popular structural motives in durgs and natural products. Herein, we developed a room temperature and robust synthesis of benzofused lactams through cobalt(III)‐catalyzed C(sp2)−H amidation. In this protocol, in‐situ formation of Cp*Co(III)(ligand) catalyst from Cp*Co(CO)I2 and ligand simplify the synthetic effort of cobalt
