Arbuzov reactions (the treatment of phosphites with alkyl halides to yield monoalkyl phosphonates) have been compared with similar transformations of derivatives of other / -block elements of variable valency. ° Transformations of organic derivatives of N, P, As, S, Sb, and other elements, accompanied by a change in the valency of the heteroatom, are considered. The uniqueness of the Arbuzov reaction is explained by specific features of P derivatives, leading to prevailing occurrence of this reaction, in contrast to derivatives of other p-block elements of variable valency, in which competing transformations prevail. 

In order to better appreciate the source and control of space in the following dimensional sequence (i.e., Picoscopic — Nanoscopic -> Microscopic - Macroscopic) it is necessary to reflect back to fundamental atomic level aufbau (build-up). Figure 6 illustrates a hierarchy of elements that are critical to the repertoire of the organic chemist as well as the picoscopic/sub-nanoscopic building blocks and functional groups that can be derived from them.
