Abstract
Reactions of several phenyl ethers and an ester with pyridine hydrogen iodide were examined under various conditions as model studies for the recently reported molecular weight reduction of a fraction of Illinois No. 6 coal by hydrogen iodide in pyridine at 50°.
No ether or ester cleavage was observed at 60-80° in pyridine, acetonitrile, ethanol or the absence of solvent. Sealed tube reactions at 210° resulted in cleavage to phenol plus various hydrocarbon and alkyl halide products. Pyridine and benzyl phenyl ether at 210° produced no cleavage in the absence of hydrogen iodide.
Syntheses of crystalline pyridine hydrogen iodide and pyridine hydrogen bisulfate as well as cyclohexyl phenyl ether are described.
