Popis: A palladium/TADDOL-derived phosphonate catalyzed desymmetric ring-opening coupling bewteen prochiral silacyclobutanes and alkyl terminal alkynes was developed. This catalytic system facilitates the formation of optically active allyl vinylsilane compounds featuring a quaternary silicon-stereogenic center, achieving good to high yields and moderate to good enantiomeric ratios. This approach significantly broaden the scope of ring-opening desymmetrization reactions involving silacyclobutanes under transition metal catalysis.
