FREE-RADICAL REACTIONS OF 1,1,2-TRICHLOROPROPENE. I. PHOTOOLIGOMERIZATION OF 1,1,2,-TRICHLOROPROPENE

Martynov, A.V.,Mirskova, A. N.,Vitkovskii, V. Yu.,Voronkov, M. G.

, p. 631 - 634 (2007/10/02)

The UV irradiation of 1,1,2-trichloropropene leads to the production of a complex mixture of products with the molecular formulas C6H5Cl5, C6H4Cl6, C6H5Cl7 and also CH3CCl2COOH and CH3CCl2COCl.By chromatomass spectrometry and IR and PMR spectroscopy it was shown that in addition to the acid and the acid chloride the main products are 1,1,2,4,5,6-hexachloro-1,4-hexadiene CCl2=CClCH2CCl=CClCH2Cl and 1,1,2,4,4,5,5-heptachloro-1-hexene CCl2=CClCH2CCl2CCl2CH3.
