The preparation is described of 6- and 7-chlorofurazanobenzofuroxan. Each exists as a mixture of two tautomeric forms at room temperature and these were identified by n.m.r. spectroscopy. Attempts to interconvert the two isomers thermally were unsuccessful.
描述了6-和7-氯呋喃并呋喃苯并呋喃的制备。每种在室温下以两种互变异构形式的混合物形式存在,并通过核磁共振光谱法鉴定。尝试热交换两种异构体均未成功。
