The reactions with CHjF of photochemically produced tritium atoms from TBr have been studied at various v+xvelengths. The energy threshold is lower and the relative yield higher for F replacement than for H repkement in CHaF. These near-threshold substitution reactions are consistent with an inversi

✦ Synopsis
Acyl chlorides are split into acyl and chlorine radicals by light of wavelength 254 my. Since the dissociation energy of the chlorine-hydrogen bond is considerably larger than that of the acyl-hydrogen bond, substitution of the substrate by acyl radicals is observed on irradiation of acid chlorides. On irradiation of acetyl chloride the following reactions take place:

## Abstract The Hg(6^3^__P__~1~) photosensitized decompositions of 3‐methyl‐1‐butene, 2‐methyl‐2‐butene, 3,3‐dimethyl‐1‐butene, and 2,3‐dimethyl‐1‐butene have been used to generate 1‐methylallyl, 1,2‐dimethylallyl, 1,1‐dimethylallyl, and 1,1,2‐trimethylallyl radicals in the gas phase at 24 ± 1°C. F
