A hydrogen transfer reaction may be more efficiently promoted by using a metal complex represented by Formula (2):
(wherein, R1 to R8 are the same or different, and each represents a hydrogen atom, a substituted or unsubstituted alkyl group or the like; or wherein; R1 and R2, R2 and R3, R3 and R4, R4 and R5, and R5 and R6 are respectively bonded to each other to form a bivalent hydrocarbon group;
R9 are the same or different, and each represents an alkyl group or cycloalkyl group;
M is ruthenium (Ru) or the like;
X is a ligand; and
n is 0, 1 or 2).
More specifically, the metal complex enables a hydrogenation reaction of various substrates having a stable carbonyl group or the like to be advanced with a high yield under mild conditions.
一个氢转移反应可能通过使用由式(2)表示的金属配合物更有效地促进:
(其中,R1至R8相同或不同,每个代表氢原子,取代或未取代的烷基基团或类似物;或其中;R1和R2,R2和R3,R3和R4,R4和R5,以及R5和R6分别相互连接以形成二价碳氢基团;
R9相同或不同,每个代表烷基基团或环烷基基团;
M为钌(Ru)或类似物;
X为配体;以及
n为0、1或2)。
更具体地说,该金属配合物使具有稳定羰基团或类似物的各种底物的氢化反应在温和条件下高产率地进行。
