Method for preparing 1,1,1,3,3-pentachlorobutane

The invention discloses a method for preparing 1,1,1,3,3-pentachlorobutane. According to the method, carbon tetrachloride and 2-chloropropene have a telomerization reaction through a telomerization catalyst to prepare 1,1,1,3,3-pentachlorobutane, wherein the reaction temperature ranges from 25 DEG C to 100 DEG C, and the reaction time ranges from 0.5 h to 5 h. The telomerization catalyst is prepared from a main catalyst, an auxiliary catalyst and an organic active agent, wherein halogenated copper salt or halogenated iron salt serves as the main catalyst, alkyl phosphate or diisopropyl phosphate or organic tertiary amine serves as the auxiliary catalyst, azodiisobutyronitrile, 2,2-azobis(4-methoxy-2,4-dimethylvaleronitrile), 1,1-azo-Biscyclohexanecarbonitrile, ascorbic acid, 2,3,4,5,6-5-hydroxy aldehyde, phenylhydrazine or metoxyphenol serves as the organic active agent, and the molar ratio of the main catalyst to the auxiliary catalyst to the organic active agent is 1:(0.5-20):(0.1-20). The telomerization catalyst has the advantages of being mild in reaction conditions and stable in air and can be used for catalyzing the telomerization reaction between carbon tetrachloride and 2-chloropropene to prepare 1,1,1,3,3-pentachlorobutane.

Carbonyl ylides and carbenes from thermolysis of oxadiazolines. Substituent effects on intramolecular and intermolecular reactions of carbonyl ylides

Thermolysis of a 2-methoxy-Δ3-1,3,4-oxadiazoline involves loss of N2 with formation of carbonyl ylide.The fate of the carbonyl ylide depends on its enviroment and on the other substituents present.Thus, the ylides from 2-methoxy-2,5,5-trimethyl-Δ3-1,3,4-oxadiazoline (1) and from 2-methoxy-2-(4-methoxyphenyl)-5,5-dimethyl-Δ3-1,3,4-oxadiazoline (2) are trapped very efficiently by methanol.However, the ylide from 1 is trapped much less efficiently than that from 2 by dimethylacetylene dicarboxylate, cis-1,2-dichloroethylene, or norbornadiene.A major competitive process in the case of 1 is fragmentation of the ylide to carbonyl compounds and carbenes, the latter being trapped by alkenes to form cyclopropanes.An intramolecular 1,4-H transfer is also competitive under some conditions.The ylide from 2 does not appear to fragment, nor does it undergo the 1,4-H transfer, but it cyclizes efficiently to the oxirane in the absence of trapping agents.Preliminary estimates of rate constants for cyclization of ylide from 2 to form the oxirane (kcycl31 deg C = 1.3*1E-6 s-1) and for its additions to norbornadiene and to dimethylacetylene dicarboxylate (1*1E-5 M-1s-1 and 1*1E-9 M-1s-1, respectively are reported.If it is assumed that the ylide from 1 would add to dimethylacetylene dicarboxylate with a similar rate constant, then the yield for that process can be used to place a lower limit of 1010s-1 on the rate constant for fragmentation of that ylide at 31 deg C.
