Organo elemental antimony

Some oxygen-containing heteroelement compounds, in which other elements are not coordinatively active, could be attributed to O-ligands. This group includes in particular nitrogen, phosphorus, arsenic, and antimony organo-oxides [1,3,11,112], The most studies amongst them are phosphine oxides, on whose basis complexes, with structure 295, of practically all metals have been obtained [1, vol.2 3] ... 

Arsenic, antimony, and bismuth are the metallic representatives among the fifth main-group elements. Owing to early chemotherapeutic applications a tremendous number of organo-metal derivatives has been prepared, especially of arsenic. 

Phosphorus trichloride, stannous chloride, and mercuric iodide give products of the type RHgX with mercury dimethyl, but cadmium iodide does not yield the above type, and antimony trichloride yields an organometallic eoznpound. Mercury diethyd reacts with the trichlorides of phosphorus, arsenic, and antimony to yield organo derivatives of these elements, aird with mercuric chloride it gives ethyl mercuric chloride. 

It will be seen that a number of tlie reactions afford means of obtaining organo-tballium derivatives. In the case of organo compounds of the elements of Group V., it may be stated that phosphorus and antimony chlorides yield no organo-thallium derivatives, whereas arsenic and bismuth chlorides are capable of yielding eompoimds of the type... 

There is an extensive literature on the chemistry of As, Sb, and Bi in addition to recent editions of standard textbooks, there is a book edited by Norman, which includes a chapter devoted to the coordination chemistry of these elements, as well as the article by McAuliffe in Comprehensive Coordination Chemistry (CCC, 1987). The vast organic chemistry of these elements falls outside the scope of the present chapter. Sources providing recent coverage of the organic chemistry include chapters by Wardell, in Comprehensive Organometallic Chemistry I and II, a volume in the Patai series The Chemistry of Organic Arsenic, Antimony and Bismuth Compounds), and chapters in Norman s book. These texts also list many reviews on specific classes of organo-derivatives.
