100 responded to the intenaity of this multiplet. Also the lower intensit> of the methyl and niethjlene doublets for compound VI1 corresponded to the low intensity of the multiplet at 8 = 4.98 p.p.m. for CH,==C.

The phosphorus trichloride-rinI.lc)clohexene experiment was run i n the batch process apparatus described above. A charge of 51.5 g. of vinylcyclohexene, freshly washed with ferrous sulfate solution and disti!led o\er sodium and 385 g. of redistilled phosphorus trichloride, was flushed K i t h nitrogen and then irradiated

Phosphorus trichloride reactions with the olefins listed in Table 11 2nd with those reported above to yield little or no product were r u n in the batch apparatus in a maimer similar to the experiments with isobutylene and vinylcyclohexene above except that product residues after removal oi'unreacted reagents were not distilled. An attempt to distill a portion of the phosphorus trichloride- vinyl acetate product under vacuum resulted in decomposition.
