Abstract
Horner-Wadsworth-Emmons reaction of stannylvinylphosphonates with aldehydes and mild thermal cyclisation provides disubstituted arylstannanes. Subsequent Stille coupling leads to regiospecific synthesis of m- and p-terphenyls.
Key words
Horner-Wadsworth-Emmons - Palladium coupling arylstannanes - Stille reaction - terphenyls
