Recently,'we found that primary and secondary alcohols were oxidized to aldehydes and ketones when treated in the dark with N-iodosuccinimide (NIS), silver acetate, and heat. Tertiary alcohols were unaffected when subjected to these same reaction conditions. In this new study we have oxidized four symmetrical diprimary diols (1, 4-butanediol, 1, 5- pentanediol, 1, 6-hexanediol, and 1, 2-benzenedimethanol) and one unsymmetrical ...
