Inter- and innermolecular reactions of chloro(phenyl)carbene

Supramolecular photolyses of 3-chloro-3-phenyl-3H-diazirine (8) were performed within cyclodextrin (CyD) hosts to determine whether these toroidal inclusion compounds could alter the reactivity of the ensuing carbene reaction intermediate, chloro(phenyl)carbene (9). Remarkably, no intramolecular products stemming from carbene 9 could be detected. Instead, modified CyDs were formed via so-called innermolecular reactions. Hence, diazirine 8 was photolyzed in various conventional solvents to gauge the intermolecular reactivity of carbene 9. Relevant results were used to rationalize the CyD innermolecular reaction products.

THIOCYANATO-, BROMO-, AND CHLOROARYLATION OF TRICHLOROETHYLENE

By reactions of arenediazonium salts with trichloroethylene in aqueous acetone in the presence of alkali metal thiocyanates, bromides, or chlorides, catalyzed by Cu(II) or Fe(II) salts, we synthesized 1-thiocyanato(bromo, chloro)-1,2,2-trichloro-2-arylethanes.These were treated with alcoholic potassium hydroxide to give α,β,β-trichlorostyrenes.Trichloroethylene is less reactive in the anionarylation than vinylidene and vinyl chlorides.

Studies on the rearrangement of (trichloromethyl)carbinols to α-chloroacetic acids

Phenyl(trichloromethyl)carbinol undergoes an unimolecular, predominantly intramolecular conversion into potassium α-chlorophenylacetate on stirring with 10percent aqueous potassium hydroxide at 0 deg C for several days.Besides providing an interesting example of a 1-2 chlorine shift, the reaction is of potential importance for the synthesis of α-chloro acids.The study of a variety of (trichloromethyl)carbinols shows the reaction is general for secondary (trichloromethyl)carbinols as well as trichloroethanol.The mechanism of the reaction involves the preliminary formation of an epoxide.Several mechanisms are considered for the conversion of the epoxide to the α-chloroacetate anion, but none accounts for all of the experimental facts.Tertiary carbinols break down at the epoxide stage into a ketone and carbon monoxide.
