24 - 081Reactions of Vinyl and Aryl Triflates with Hypervalent Tin Reagents.— Vinyl and aryl triflates are arylated or benzylated in good yields andshort reaction times using hypervalent tin reagents as arylating or benzylatingagents. This represents an important improvement and a useful supplementof the Stille coupling reaction. The presented data complete previouslyreported applications of hypervalent tin reagents in arylation and benzylationreactions. — (GARCIA MARTINEZ, ANTONIO; BARCINA, JOSE OSIO;COLORADO HERAS, MARIA DEL ROSARIO; DE FRESNO CEREZO,ALVARO; Organometallics 20 (2001) 5, 1020-1023; Dep.
