An efficient iron phthalocyanine catalyzed method was developed for direct oxidative coupling of alcohols with amines to afford corresponding imines. The present protocol is applicable to various substituted aromatic and aliphatic alcohols and amines. The reaction is believed to proceed via activation of alcohols by iron phthalocyanines through Lewis acid-base interaction to form aldehydes, which by nucleophilic attack of amines are converted into the corresponding imines.

FeCl3-catalyzed three-component tandem condensation/addition/ cyclization/oxidation reactions of aldehydes, terminal alkynes, and primary amines have been developed. The processes can provide a diverse range of quinoline derivatives in good yields from simple starting materials. A possible reaction mechanism was proposed.

Palladium nanoparticles supported over poly(vinyl)chloride matrix (PVC-Pd0) are prepared through an efficient and inexpensive protocol. The catalyst has been characterized by XRD, SEM and TEM and its utility for the reduction of a range of functional groups as well as for the removal of some common protecting groups employed in peptide chemistry is demonstrated.
Synthesis of imines from nitrobenzene and TiO2 particles suspended in alcohols via semiconductor photocatalysis type B
Rios-Bern?, Omar,Flores, Sergio O.,Córdova, Iván,Valenzuela, Miguel A.
experimental part, p. 2730 - 2733 (2010/06/14)
UV irradiation on a non-aqueous suspension of titanium dioxide with nitrobenzene and different alcohols in deaerated conditions produces imines and aniline as main products. The conversion of nitrobenzene and the corresponding selectivity of imines or aniline depend on the type of alcohol used. A low conversion (3-12%) and selectivity close to 100% to imines were obtained with methyl, ethyl, or propyl alcohol. Otherwise, using i-propanol only aniline was detected with a conversion of 13%. Finally, a mixture of aniline and imines was formed employing n-butyl, n-amyl, and i-amyl alcohols with the higher conversion (～50%).
Preparation of Activated Imines and Their Condensation with Allylstannanes: Stereoselective Synthesis of 1,2-Amino Alcohols

A modified Wadsworth-Emmons reaction affords hitherto inaccessible imines derived from aliphatic aldehydes and aromatic amines.Such highly activated imines condense rapidly and stereoselectively with oxygenated allylstannanes, at -78 deg C, under the infl
SYNTHESIS OF ALIPHATIC-AROMATIC AMINES IN THE PRESENCE OF THE COMPLEXES OF PALLADIUM IONS WITH POLYTRIMETHYLOLMELAMINE

The complexes of palladium ions with polytrimethylolmelamine effectively catalyze the hydrogenation amination of aldehydes with nitrobenzene under mild conditions (1 atm of hydrogen, 18-50 deg C).The intermediate products in the amination of aldehydes with nitro-, azo-, and azoxybenzene are phenylhydroxylamine, aniline, and the corresponding azomethine.
