Preparation of 1,1-Dichloroalkyl Peroxycarboxylates

1,1-Dichloroethyl hydroperoxide (4a) and 1,1-dichloropropyl hydroperoxide (4b) react with a number of acyl chlorides yield 1,1-dichloroalkyl percarboxylates 6a-q.The sensitivity of 4 to hydrolysis and thermal decomposition as well as the ready decomposition of some of the peresters lead to by-products.In certain cases the preparation of 6 does not require the isolation of the hydroperoxide 4.Thus, 6c and e are produced in satisfactory yields when ozonolysis of 2,3-dichloro-2-butene (1a) is carried out in excess propionyl or butyryl chloride.The 1,1-dichloroethyl peroxide ion (7) is presumed to be the intermediate in the ozonolysis of 1 a in the presence of tetraalkylammonium chloride.
