Cylisation reactions of 2-substituted biphenyl-2′-yldiazonium salts leading to O-alkyldibenzofuranium and S-alkyl-dibenzothiophenium salts: modified meerwein reagents
摘要:
The preparation of 2-amino-2'-methoxybiphenyl and 2-amino-2-thiomethoxybiphenyl and analogues and their transformation into diazonium salts and hence into dibenzofuranium and dibenzothiophenium salts is described together with their use as alkylating agents.

The 2‐(neopentylsulfinyl)aniline‐promoted rapid palladium‐catalyzed C–H acetoxylation and alkenylation of arylacetamides is reported. In the alkenylation, easily available cyclopropanols were employed as a source of functionalized vinyl ketones.
