| Popis: | A novel diiron S-(−)-1-phenylethylazadithiolate complex, Fe 2 [( μ -SCH 2 ) 2 NCH(CH 3 )Ph](CO) 6 ( 1 ), has been prepared by the condensation of Fe 2 ( μ -SH) 2 (CO) 6 , CH 2 O and S-(−)-1-phenylethylamine. Furthermore, the reaction of complex 1 and phosphine ligands (PPh 3 , P(C 6 H 4 -4-F) 3 , dppe) in the presence of the decarbonylation agent Me 3 NO·2H 2 O resulted in the formation of the phosphine-substituted diiron S-(−)-1-phenylethylazadithiolate complexes Fe 2 [( μ -SCH 2 ) 2 NCH(CH 3 )Ph](CO) 5 (PPh 3 ) ( 2 ), Fe 2 [( μ -SCH 2 ) 2 NCH(CH 3 )Ph](CO) 5 [P(C 6 H 4 -4-F) 3 ] ( 3 ) and {Fe 2 [( μ -SCH 2 ) 2 NCH(CH 3 )Ph](CO) 5 } 2 (Ph 2 PCH 2 CH 2 PPh 2 ) ( 4 ). Complexes 1 – 4 have been fully characterized by elemental analysis, FTIR and NMR ( 1 H, 13 C, 31 P) spectroscopies, and for 1 , 2 and 4 by X-ray crystallography. Moreover, complexes 1 and 2 were found to be catalysts for hydrogen production in the presence of acid under electrochemical conditions. According to the electrochemical observations, a possible catalytic mechanism for complexes 1 and 2 was proposed. |
