Reactions with halides

These compounds generally exist in carbonyl forms. The oxygen function can be converted into halogen by phosphorus halides. Reactions with electrophiles are quite complex. Thus urazole (511) reacts with diazomethane quickly to yield (512), which is more slowly converted into (513). 1-Phenylurazole gives (514) however, 4-phenylurazole yields (515). Oxadiazolinones of type (516) can be alkylated at both O- and N-atoms.

Gold reacts with chlorine, bromine and iodine at elevated temperatures forming the corresponding halides. Reaction with fluorine is very slow. In the presence of moisture, gold reacts with chlorine, bromine and iodine at ordi-... 

At ordinary temperatures tin is stable in air. It actually forms a very thin protective oxide film. In powder form, and especially in the presence of moisture, it oxidizes. When heated with oxygen it forms tin(IV) oxide, Sn02.Tin reacts with all halogens forming their halides. Reaction with fluorine is slow at ordinary temperatures however, chlorine, bromine and iodine readily react with the metal...

The majority of the acyl halide reactions with episulfides have involved ethylene sulfide and propylene eulfide with C -Ca aliphatic acyl halides and have given 2-haloalkyl thiolesterB in good yields. A survey of these reactions is summarized in Table 16.
