Abstract

Abstract : The catalytic enantioselective cyanosilylation of ketones with highly reactive lithium dicyanotrimethylsilicate involves two lithium centers and is represented by Mr. Fukusuke holding two Engi‐kumades (bamboo rakes). In their Communication onpage 4021 ff., K. Ishihara and co‐workers report on an acid–base cooperative catalytic system, an ( R )‐BINOL‐derived lithium phosphoryl phenoxide aqua complex, which activates both the ketone and lithium dicyanotrimethylsilicate.
