General description
Cyclobutyl chloride is formed by rearrangements concerted with fragmentation of cyclopropylmethoxychlorocarbene and cyclobutoxychlorocarbene. The thermal decomposition of cyclobutyl chloride was investigated over the temperature range of 892-1150K using very low-pressure pyrolysis technique.

Competitive unimolecular reactions at low pressures. The pyrolysis of cyclobutyl chloride.

Fragmentations of cyclopropylmethoxychlorocarbene (6) and cyclobutoxychlorocarbene (10) lead to rearrangments that afford mixtures of cyclopropylmethyl chloride (7), cyclobutyl chloride (8), and 3-butenyl chloride (9). Isotopic substitution studies show that these rearrangments are accompanied by partial exchange of the methylene groups
