摘要: Abstract The ring-closure reactions of (W(CO)5L were studied as a function L (L = en, bpy, dab), temperature and pressure. corresponding observed rate constants exhibit marked dependence on the nature L, volumes activation are throughout significantly negative. These observations imply that proceed via an associative mode activation.
