Fragmentation of cyclobutoxychlorocarbene: The cyclopropylcarbinyl/cyclobutyl cations revisited

Fragmentations of cyclobutoxychlorocarbene (13, kfrag= 7.1 × 105 s-1) and cyclopropylmethoxychlorocarbene (14, kfrag = 7.6 × 105 s-1) in MeCN proceed to tight and distinct [R+ OC Cl-] ion pairs, which collapse to different distributions of cyclopropylcarbinyl, cyclobutyl and allylcarbinyl chlorides. B3LYP/6-31G* calculations support these conclusions, affording computed fragmentation activation energies of 6.4 (13) and 3.0 (14) kcal mol-1.

FRAGMENTATION OF CYCLOPROPYLMETHOXYCHLOROCARBENE: FORMATION OF CYCLOPROPYLCARBINYL/CHLORIDE ION PAIRS

The decomposition of cyclopropylmethyloxychlorodiazirine in MeCN proceeds via N2 and CO loss, mainly to tight cyclopropylcarbinyl cation-chloride anion pairs that collapse to C4 chlorides with substantial skeletal and label retention; the ion pairs can be intercepted by ethanol with less skeletal retention.
