subsequent preparation of its 2-aryl-methylation products are reported. The Hammett ϱ-constant has been evaluated (ϱ = 2.2) and a tentative description of the transition state for the benzylation reaction of the metalated oxazine is proposed.
据报道用
正丁基锂将2-乙基-4,4,6-三氢乙基-5-,6-二氢-4H-1,3-恶嗪
金属化并随后制备其2-芳基甲基化产物。已经评估了Hammettε-常数(ε= 2.2),并提出了
金属化恶嗪苄基化反应的过渡态的初步描述。
