General considerations are outlined for a reagent to extract oxygen from organic molecules by an equivalent of dehydration.Reagents, (R3P+)2O, 2OTf-, were created for the purpose and subjected to a preliminary study.They were found to convert carboxylic acids readily and rapidly to anhydrides, esters, amides, amidines, benzimidazoles, and cyclic aryl ketones in good yields.

A set of "phosphonium anhydride"reagents is shown to have virtually ideal properties as selective oxygen extractors for net dehydration reactions in a series of illustrative examples.
