Visible Light-Driven Decarboxylative Alkylation of Aldehydes via Electron Donor–Acceptor Complexes of Active Esters

There are some synthesis methods from widely available aldehydes to the corresponding ketones, however, they involved in multistep reactions with Grignard’s reagents or transition metal catalysts. In this paper, we have developed photocatalyst-free and visible light-driven decarboxylative alkylation of pyridinaldehydes. The photochemical reactions are initiated via photoinduced single electron transfer from triethylamine to N-hydroxyphthalimide esters in electron donor–acceptor complexes. This photochemical method can achieve to translate 15 pyridinaldehydes and 11 2-quinolinaldehydes to the corresponding ketones. Furthermore, this strategy can also achieve two other transformations, disulfanes to aryl sulfides and a styrene sulfone to the alkyl-substituted alkene.

Transition metal complex and application thereof

The invention relates to a transition metal complex and application thereof. The transition metal complex has a structural general formula shown as chemical formula (1). The transition metal complex is used as a light-emitting layer doping material, and c

Pd-Catalyzed Alkylation of (Iso)quinolines and Arenes: 2-Acylpyridine Compounds as Alkylation Reagents

The first Pd-catalyzed alkylation of (iso)quinolines and arenes is reported. The readily available and bench-stable 2-acylpyridine compounds were used as an alkylation reagent to form the structurally versatile alkylated (iso)quinolines and arenes. The method affords a convenient pathway for the introduction of alkyl groups into organic molecules.

Facile one-pot synthesis of [1,2,3]triazolo[1,5-a]pyridines from 2-acylpyridines by copper(II)-catalyzed oxidative N-N bond formation

An efficient and simple method for the synthesis of various [1,2,3]triazolo[1,5-a]pyridines has been established. The method involves a copper(II)-catalyzed oxidative N-N bond formation that uses atmospheric oxygen as the terminal oxidant following hydrazonation in one pot. The use of ethyl acetate as the solvent dramatically promotes the oxidative N-N bond-formation reaction and enables the application of oxidative cyclization in the efficient one-pot reaction. A mechanism for the reaction was proposed on the basis of the results of a spectroscopic study. In the same pot: [1,2,3]Triazolo[1,5-a] pyridines are synthesized from the corresponding 2-acylpyridines by a one-pot method, consisting of hydrazonation followed by oxidative cyclization through copper(II)-catalyzed N-N bond formation (see scheme).

Facile preparation of aromatic ketones from aromatic bromides and arenes with aldehydes

Aromatic ketones were efficiently prepared in good yields by the reactions of aryl bromides with n-BuLi, followed by the reactions with aromatic aldehydes or aliphatic aldehydes and the subsequent treatment with molecular iodine and K2CO3, in a one-pot method. The same treatment of arenes, instead of aromatic bromides, also provided the corresponding aromatic ketones in good yields. Using these methods, various diaryl ketones and alkyl aryl ketones bearing electron-rich aromatics and electron-deficient aromatics could be prepared efficiently by a simple, transition-metal-free, and therefore environmentally benign experimental procedure.

Double duty for cyanogen bromide in a cascade synthesis of cyanoepoxides

An unprecedented reaction mode of cyanogen bromide has been discovered. Under basic conditions, cyanogen bromide acts as an equivalent of both Br + and CN- to convert enolizable ketones into the corresponding cyanoepoxides in good yields. This unique reaction mode provides new, one-pot access to densely substituted cyanoepoxides from easily available ketones (see scheme). Copyright

2-Pyridyl and 3-pyridylzinc bromides: direct preparation and coupling reaction

A facile synthetic approach to the direct preparation of 2-pyridyl and 3-pyridylzinc bromides has been demonstrated using Rieke zinc with 2-bromopyridine and 3-bromopyridine, respectively. A variety of different electrophiles have been coupled with the resulting organozinc reagents to give the corresponding cross-coupling products in moderate to good yields.

Studies on Organometallic Compounds. III. Reaction of Trimethylstannylazines with Acyl Chlorides. A Novel C-C Bond Formation of Pyridine Nuclei

Introduction of an acyl group at the α-, β-, and γ-positions of pyridine nuclei was accomplished. 2-Trimethylstannyl-pyridine and -quinoline and 1-trimethylstannylisoquinoline directly reacted with various acyl chlorides to give the corresponding 2-pyridyl, 2-quinolyl, and 1-isoquinolyl ketones, respectively.Reaction of 3-trimethylstannylpyridine, -quinoline, and -isoquinoline with acyl chlorides proceeded smoothly under catalysis by PdCl2 or PdCl2(PPh3)2 to afford the corresponding ketones in good yields.Similary, 4-pyridyl, -quinolyl, and -isoquinolyl ketones were prepared from corresponding 4-trimethylstannyl derivatives and acyl chlorides.Keywords--trimethylstannylazine; palladium-catalyzed reaction; acylation; palladium dichloride; dichlorobis(triphenylphosphine)palladium(II)

A SIMPLE METHOD FOR INTRODUCTION OF ACYL GROUPS INTO PYRIDINE NUCLEI VIA TRIMETHYLSTANNYL-PYRIDINES AND QUINOLINES.

The 2-trimethylstannyl (TMSn) derivatives of pyridine and quinoline were directly treated with acyl chlorides to afford the corresponding 2-acyl-pyridines and -quinolines in good yields.On the other hand, replacement of the 3- and 4-TMSn groups by acyl groups was satisfactorily achieved by catalysis of palladium compound such as PdCl2 or PdCl2(PPh3)2.
