[NO]- and [NN]-coordination mode rhodium complexes based on a flexible ligand: Synthesis, reactivity and catalytic activity

A flexible [NON]-type ligand was prepared via a stepwise method. Air- and moisture-stable LL- (N,O-coordination mode) (1) and LX-type (N,N-coordination mode) (2) rhodium(i) complexes were synthesized based on this flexible ligand under different reaction conditions. The two rhodium complexes were isolated in good yields and characterized by elemental analysis and IR and NMR spectrometry. The molecular structures of complexes 1 and 2 were confirmed by single-crystal X-ray analysis. The cationic rhodium complex was shown to be a good catalyst for the hydrogenation of acetophenone derivatives without pre-dried solvents and reagents. Good efficiency was achieved for a series of substrates with either electron-donating or electron-withdrawing groups.

Daminin, a bioactive pyrrole alkaloid from the Mediterranean sponge Axinella damicornis

The isolation and characterization of the known pyrrole alkaloid agelongine (6) and of the new natural product daminin (7), the bromine-free analogue of 6, from a specimen of the marine sponge Axinella damicornis is described. Compound 7 showed significant neuroprotective properties. Moreover, for the supply of sufficient material for future medicinal investigations, a short total synthesis of 7 was developed.

Alternating current electrolysis for organic electrosynthesis: Trifluoromethylation of (hetero)arenes

Paired electrolysis has a limited reaction scope for organic synthesis because it is often not compatible with reactions involving short-lived intermediates. We addressed this limitation using alternating current electrolysis (ACE). Using trifluoromethyla

N,N-coordination Rh complex as well as synthesis method and application thereof

The invention belongs to the technical field of synthesis of organic metal compounds and particularly relates to an N,N-coordination Rh complex as well as a synthesis method and an application thereof. Firstly, a ligand is synthesized from methyl 1H-pyrrole-2-carboxylate as an initial raw material and further reacts with Rh(COD)2Cl, and a metal complex with Rh as a central atom is obtained. The synthesis method is simple, the complex as a catalyst can be used for catalyzing a series of reductive amination reactions of derivatives of acetophenone and aniline, and the product yield is good and is 90% or above.
