Highlights of Oxygen Chemistry

Oxygen is the most abundant element on Earth s surface, occurring in air as the free element, combined with hydrogen in water, and combined in innumerable oxides, silicates, carbonates, and phosphates. Virtually all O2 has a biological origin, having been formed for billions of years by photosynthetic algae and multicellular plants in an overall equation that looks simple but involves many steps  

The reverse process occurs during combustion and respiration. 

Every element (except He, Ne, and Ar) forms at least one oxide, many by direct combination. For this reason, a useful way to classify elements is by the acid-base properties of their oxides. The oxides of Group 6A(16) exhibit expected trends down the group, with SO3 the most acidic and P0O2 the most basic.

Direct insertion into an X—H a bond constitutes the highlight of dioxirane chemistry . Besides the insertion of a dioxirane oxygen atom into an alkane acH bond, for practical purposes a most valuable oxyfunctionalization, also the more facile insertion into the asiH bond is known, a convenient and chemoselective method of preparing silanols.
