A simple and efficient transprotection of aryl methyl ether to aryl benzoate under microwave activation

A simple and efficient method for the transprotection of aryl methyl ether to easily cleavable arylbenzoate mediated by microwave activation has been developed. One important feature of this method is its high tolerance towards sensitive functionalities and to some extent to bulky environment.

NOVEL DENDRIMER HAVING ALKYL SHELL STRUCTURE AND PRODUCTION METHOD OF METAL SUB-NANOPARTICLE

PROBLEM TO BE SOLVED: To provide a novel dendrimer with which aggregation of metal clusters can be suppressed in synthesizing the metal clusters by reducing accumulation bodies comprising a metal salt compound accumulated on the dendrimer and with which aggregation of the accumulation bodies in a solvent can also be suppressed, and to provide a production method of sub-nanoparticles using the novel dendrimer. SOLUTION: A dendrimer of the invention has at least one dendritic branch structure selected from a phenylazomethine skeleton and a carbazole skeleton as a constitutional unit, and is characterized as having alkyl groups or alkoxy groups comprising a 6-36C straight chain alkyl section or a 6-36C straight chain alkoxy section as main chains on all or a part of a plurality of phenyl portions to be terminals of the dendritic branch structure, and the alkyl groups or the alkoxy groups form a shell covering the dendritic branch structure.

Divergent approach for synthesis and terminal modifications of dendritic polyphenylazomethines

(Chemical Equation Presented) In the past, dendritic polyphenylazomethines (DPA) have been synthesized via the convergent method. However, the convergent method has problems such as difficult terminal-group modifications and an increased number of steps.
