Latest Patents

Jun Young Choi holds a patent for a method titled "Cross-coupling reaction of organosilicon nucleophiles." This invention focuses on improved methods for generating a —C—C— bond through the cross-coupling of a transferable group with an acceptor group. The transferable group is a substituent of an organosilicon nucleophile, while the acceptor group is provided as an organic electrophile. The reaction is catalyzed by a Group 10 transition metal complex, particularly a palladium complex. The methods utilize improved organosilicon nucleophiles that are easily prepared, yield high product outputs, and exhibit high stereoselectivity. Additionally, the invention employs activating ions such as halides, hydroxide, hydride, and silyloxides. Specific embodiments include the use of siloxanes, particularly cyclic siloxanes. The combination of these cross-coupling reactions with ring-closing metathesis, hydrosilylation, and intramolecular hydrosilylation reactions offers valuable synthetic strategies.
