β-phenylethylamines, indolines and isoquinolones via hydroamination of styrenes by microwave irradiation
Seijas,Vázquez-Tato,Martínez
, p. 875 - 877 (2001)
Microwave irradiation promotes hydroamination of styrenes. This method can be used as a direct way of producing different kinds of bioactive compounds: open chain compounds like β-phenylethylamines or cyclized products like indolines or isoquinolones.

Six palladium(II) complexes with benzimidazole-based N-heterocyclic carbene ligands were synthesized by transmetallation reactions between silver(I) N-heterocyclic carbene complexes and PdCl2(PhCN)2. The complexes were characterized by physicochemical and spectroscopic methods. The palladium complexes were tested as catalysts for intermolecular hydroamination reactions of styrene with various anilines in ionic liquids under both conventional and microwave heating. All of these complexes proved to be catalytically active in these reactions. The anti-Markovnikov addition products were selectively obtained by using 1?mol% of the palladium complex.

The complexes [Ti(NMe2)2(pmpmi)] [H2pmpmi = (2-pyrrolylmethene)-(2-pyrrolylmethyl)imine], [Ti(NtBu)(pmpmi)(py) 2], [Ti(NtBu)(pmpmi)(dpy)] and [Ti(NPh)(pmpmi)(py) 2] have been prepared, characterised and shown to be pre-catalysts for the hydroamination of phenylacetylene with aniline and p-chloroaniline. The X-ray structures of [Ti(NMe2)2(pmpmi)], [Ti(N tBu)(pmpmi)(dpy)] and [Ti(NPh)(pmpmi)(py)2] have been determined.

We have developed a two-step protocol for iodotrimethylsilane-mediated deoxy-functionalization of primary and secondary alcohols to afford products containing a C?N, C?S, or C?O bond. In the first step the alcohol undergoes iodination with iodotrimethylsilane, and in the second, the iodine atom is replaced by a N, S, or O nucleophile. Compared with traditional Mitsunobu reaction, non-acidic pre-nucleophiles can be used, and the reaction proceeds with retention of configuration. This operationally simple, highly efficient protocol can be used for some natural products and small-molecule drugs containing hydroxy-group.
A base-free Chan–Lam reaction catalyzed by an easily assembled Cu(II)-carboxylate metal-organic framework
Ma, Ruixuan,Qin, Jianhua,Shi, Lei,Zhang, Xinhai
, p. 795 - 799 (2021/07/06)
A new copper(II) metal-organic framework is constructed as a sustainable copper heterogeneous catalyst. Cu-DPTCA, with high catalytic activity, can effectively promote the Chan–Lam coupling reaction of arylboronic acids and amines without adding any base or additive.
Photocatalytic one-pot multidirectional N-alkylation over Pt/D-TiO2/Ti3C2: Ti3C2-based short-range directional charge transmission
