Abstract
Rhodium-catalyzed transannulation of 1,2,3-triazoles and ring-opening reactions of epoxides is described. A number of 3,4-dihydro-2H-1,4-oxazines are obtained in moderate yields probably involving generation of α-imino rhodium(II) carbene species.
摘要
铑催化的 1,2,3-三唑的 transannulation 和环氧化物的开环反应被描述。大量的 3,4-二氢-2H-1,4-恶嗪以中等产率得到，可能涉及α-亚氨基铑(II)卡宾物种的生成。
