The rate constant for the unimolecular ringopening of the 2,2-difluorocyclopropylcarbinyl radical was determined via its competitive bimolecular trapping by TEMPO. The value of this rate constant (3.4 x 10(11) s(-)(1) at 99.3 degrees C) is about 500 times larger than that of the parent, unfluorinated radical and about 5 times smaller than that of the trans-2-phenylcyclopropylcarbinyl radical.
2,2-二氟环丙基羰基的单分子开环的速率常数是通过TEMPO竞争性的双分子捕获来确定的。此速率常数的值(在99.3摄氏度下为3.4 x 10(11)s(-)(1))约为母体,未氟化基团的500倍,是反式2的约5倍。 -苯基环丙基羰基。
