Process for production of mono-substituted alkylated compound using aldimine or derivative thereof
TL;DR: In this paper, the process of alkylating an aldimine-type Schiff base in a medium in the presence of an optically active quaternary ammonium salt phase-transfer catalyst and an inorganic base is initiated, and subsequently the reaction is quenched at a time earlier than a time for completion of the stoichiometric reaction of the alkylation reaction.

Fluorotetraphenylbismuth: A New Reagent for Efficient Regioselective α‐Phenylation of Carbonyl Compounds.
TL;DR: In this article, the X-ray crystallographic characterization of fluorotetraphenylbismuth (1) has been achieved for the first time, revealing that the bismuth center of 1 adopts a distorted trigonal bipyramidal geometry with three ipso carbons at the equatorial sites and one ipso carbon and fluorine atom at the apical sites.
