摘要

One of the questions addressed in that paper concerns their fragmentation (eq l), and the authors' conclusions about fragmentation, on the basis of their studies and the literature, included the f~ llowing:~(a) Fragmentation of carbonyl ylide (X= Y= H) is endothermic by about 38 kcal/mol.(b) One amino substituent (X= NH2) decreases the thermodynamic barrier to fragmentation in either sense and path a, leading to aminocarbene, may actually be ex ...
