Metallophthalocyanines bearing substituents especially electron-withdrawing substituents are found to be efficient catalysts for cyclopropanation of alkenes with EDA. The influences of reaction conditions have been studied, leading to the highest yield of 91% for styrene by using fluorosubstituted ruthenium–phthalocyanine complex.

摘要

The reaction of [{m-h2-C(R1) CHR2}(m-CO)Fe2(CO)6] with (m-S2)Fe2(CO)6 forms (m3-S)2Fe3(CO)9 (1) and:or anionic intermediates [{m-h2-C(R1) CHR2}(m-S){Fe2(CO)6}2(m4-S)] (2) depending on the substituents R1 and R2. The actions of the anionic complexes 2 with alkyl halides, PhN2BF4 and acid chlorides give [m-h2-C(R1) CHR2](m-RS)[Fe2(CO)6]2(m4-S) (R alkyl, Ph or acyl). The structures of (m-h2-CH CHPh](m-CH2 CHCH2S)[Fe2(CO)6]2(m4-S)

摘要

The chiral mononuclear complex of Re(I)-NOBIN Schiff base (NOBIN=1-amino-10-hydroxylbinaphthyl) was synthesized via the reaction of Re(CO)5Cl and corresponding tridentate ligand in methanol. The structure analysis reveals that the central metal coordinates with nitrogen atom of imine and oxygen atom of salicylaldehyde form a six-membered ring, while the left uncoordinated phenol group adjacent to the binaphthyl backbone forms a hydrogen bonding with water molecule coordinated with the Re(I) ion. This mononuclear complex shows some catalytic ability in asymmetric epoxidation and aziridination with moderate results

摘要

Metallophthalocyanines bearing substituents are found to be efficient catalysts for nitrene transfer reactions. Under optimized reaction conditions, aziridination of alkenes and amidation of C H bonds with PhI=NTs by using 3-trifluromethylphenyoxy-substituted phthalocyanine-iron complex led to the highest yields of 90% and 85% for 4-methylstyrene and 4-ethyltoluene, respectively.

摘要

The reaction of [Et3NH] [(m-RE)(m-CO)Fe2(CO)6] (E S, Se) (1) with aryl azides gives bridging triazenido complexes (m-RE)(mp-R1C6H4N3H)Fe2(CO)6 (2-8) (2, RE ButS, R1 H; 3, RE PhS, R1 H; 4, RE ButS, R1 Cl; 5, RE ButS, R1 MeO; 6, RE PhS, R1 MeO; 7, RE PhSe, R1 H; 8, RE PhSe, R1 Cl). These complexes were characterized by elemental analyses and 1H-NMR and IR spectroscopy. The structure of complex 2, established by single-crystal X-ray diffraction analysis, shows that the triazenido ligand binds to two iron centers in a bridging bidentate fashion.
