Trichloro-phenyl methane

There is only one example of the reaction of an alkene with trichloro(phenyl)methane and reduced titanium to give 1-chloro-l-phenylcyclopropane The method appears to have potential. 

Bromo-l-chlorocyclopropanes 1 were also formed in good yield and with high selectivity via the reaction of dibromomethane with trichloro(phenyl)methane and an alkene, carried out in the presence of 60% aqueous potassium hydroxide and a catalytic amount of tetrabutylam-monium hydrogen sulfate.

Reaction of trichloro(phenyl)- or dichloro(phenyl)methane with butyllithium and 2,3-dimethylbut-2-ene affords the cyclopropane 2 in 72 and 48% yield, respectively. " ... 

Bromo-l-chlorocyclopropanes of similar boiling points to trichloro(phenyl)- and di-chloro(phenyl)methane are difficult to isolate. 

TCPMe, and 4,4, 4"-TCPM for tris(4-chlorophenyl)methane. In this chapter the abbreviations TCPM and TCPMe will be used. TCPM and TCPMe (Fig. 1) are structurally related to DDT and dicofol (l,l,l-trichloro-2,2-bis(4-chloro-phenyl)methanol) (Fig. 2).

There is certainly strong experimental evidence for the existence of radical-solvent complexes. For instance, Russell and co-workers collected experimental evidence for radical-complex formation in studies of the photochlorination of 2,3-dimethylbutane in various solvents. In this work, different products were obtained in aliphatic and aromatic solvents, and this was attributed to formation of a tt-complex between the Cl atom and the aromatic solvent. Complex formation was confirmed by flash photolysis. Complex formation was also proposed to explain experimental results for the addition of trichloro-methane radical to 3-phenylpropene and to 4-phenyl-1-butene and for hydrogen abstraction of the t-butoxy radical from 2,3-dimethylbutane. " Complexes between nitroxide radicals and a large number of aromatic solvents have been detected. Evidence for complexes between polymer radicals and solvent molecules was collected by Hatada et al.f in an analysis of initiator fragments from the polymerization of MMA-d with AIBN and BPO initiators. They discovered that the ratio of disproportionation is combination depended on the solvent, and interpreted this as evidence for the formation of a polymer radical-solvent complex that suppresses the disproportionation reaction.
