regioselective synthesis of polysubstituted quinones by the benzannulation and subsequent cross couplingreactions has been developed. Alkenyl chromium carbene complexes undergo regioselective benzannulation with 2-(trimethylsilyl)-1-phenylethyne with oxidative workup to yield silyl quinones which upon iodination with ICI produce iodoquinones. Subsequent Stille's and Suzuki's cross couplingreactions of these
