Interrelation Between the Structure and Cyclization Direction of o‐Alkynylbenzenediazonium Salts.

Abstract

Ring closure reactions O 0130 Interrelation Between the Structure and Cyclization Direction of o-Alkynylbenzenediazonium Salts. -The direction of the cyclization reaction of the intermediate diazonium salts depends on the structure of the starting anilines (I) and (III) leading either to cinnoline (II) or to indazole (IV), respectively. -(ZOL'NIKOVA, N.
