✦ Synopsis

The organocopper reagent prepared from [(2,6-xylylimino)-(trialkylsilyl)methyl]lithium undergoes the conjugate addition to a$unsaturated carbonyl compounds to produce Y-(2,6-xylylimino)-Y-(trialkylsilyl)carbonyl compounds or the organosilyl ethers of their enols.

## Abstract Rhodium fluoroapatite (RhFAP) is an efficient catalyst for conjugate addition of organoboron reagents to __α__,__β__‐unsaturated carbonyl compounds. A variety of arylboronic acids and __α__,__β__‐unsaturated carbonyl compounds were converted to the corresponding conjugate‐addition produ
