(b) Whether the reaction is the slowest, the fastest, or intermediate in rate. (c) If all three reactions have the same entropy change between the reactant and product, which reaction has the largest favorable G0. WebReactive intermediates such as nitrenes, carbenes, and radicals have been used in cyclization reactions which produce aziridines and azirines. Intermolecular aziridination reactions with nitrenes were covered in Section 1.01.9.2. Vinylnitrenes ( 118) may undergo cyclization to 2 H -azirines ( 119 ), as shown in Scheme 78. flannel pillows projects diy
