easy and direct access to POP-type osmium(II) and osmium(IV) complexes, including OsH4dbf(PiPr2)2} (dbf(PiPr2)2 = 4,6-bis(diisopropylphosphine)dibenzofuran), is reported. This tetrahydride derivative is an efficient catalyst for the selective formation of imines from alcohols and amines with liberation of H2, proving that osmium is a promising alternative to ruthenium for catalysis.
轻松直接访问POP型(II)和(IV)络合物,包括OsH 4 dbf(P i Pr 2)2 }(dbf(P i Pr 2)2 = 4,6-双(二异丙基膦) )二苯并呋喃)。该四氢化物衍生物是从醇和胺中选择性释放出H 2选择性地形成亚胺的有效催化剂,证明是钌的理想替代催化剂。
