The present invention relates to novel strigolactam derivatives of formula (I) to processes and intermediates for pre-paring them, to plant growth regulator compositions comprising them and to methods of using them for controlling the growth of plants and/or promoting the germination of seeds.

Photolysis of 3-tert-butyl-3-chlorodiazirine produces 2-chloro-3-methyl-but-2-ene and 2,2-dimethyl-1-chlorocyclopropane; the former stems from 1,2-methyl migration and nitrogen loss in the excited state diazirine, whilst the latter is a product of 1,3-CH insertion in the tert-butylchlorocarbene derived from the diazirine.
