Organometalloid compounds

Organometallic and Organometalloidal Compounds containing Fluorocarbon Radicals. 

Sulfur tetrafluoride acts as an oxidative fluorinating agent towards organometalloid compounds. Triphenylphosphane and triphenylarsane are converted at 100-150C into difluoro-triphenyl-l5-phosphane (16) and difluorotriphenyl-l5-arsane (17), respectively.219...

Chemical Abstracts (Dl) is undoubtedly the most convenient and comprehensive reference source, particularly since 1962 when a section devoted to organometallic and organometalloidal compounds was introduced. Information concerning books, review articles, and conferences is, however, extremely brief, and usually the subject matter of a particular entry must be judged solely from the title. Comparable publications in other languages include Chemisches Informationsdienst (D2) and Refera-tivnyi Zhumal, Khimya. 

Organometallic and organometalloidal compounds can lead to unexpected species that are a serious challenge to cellular systems. For example, Figures 8.2 and 8.3 show the different forms in which uranium can appear in the environment and pathways into humans.

Formation of organometalloid compounds by micro-organisms, trimethy-larsine and dimethylethylarsine, F. Challenger, C. Higginbottom and L. Ellis, J. Chem. Soc., 1933, 95. 

This journal publishes articles, notes, and communications concerned with all aspects of organometallic chemistry. Specifically, it covers synthesis, structure, bonding, chemical reactivity, reaction mechanisms, and applications of organometallic and organometalloidal compounds. Coverage includes organic and polymer synthesis, catalytic processes, and synthetic aspects of materials science and solid-state chemistry. 

Colorless, light-sensitive gas. Evolves CFg radicals when heated or irradiated with UV light and is therefore useful in the synthesis of numerous compounds of the type CFg(CF3)n X,as well as organometallic and organometalloid compounds. 

I2 + Q. and potassium carbonate at ca. 310 °C (- KF + CO + Q, study of which has led to the value 448.5 kJ mol- for the C—F bond energy [the C—F bond energy in poly(carbon monofluoride) of stoichiometry CFi.ij is reported to be ca. 480 kJ mol ]. Obviously, thermal decomposition of carbon monofluoride in the presence of suitable substrates might prove an interesting, if not useful, source of some fluorinated organic, organometallic, or organometalloidal compounds.

Seyferth, D., The Preparation of Organometallic and Organometalloidal Compounds by the Diazoalkane Method, Chem. Rev. 55 [1955] 1155/77. 

This volume is the first of a series of biennial reviews concerned with the chemistry of organic, organometallic, and organometalloidal compounds of the fluorocarbon class and of their polyfluorinated analogues. Compounds containing a low proportion of C—F bonds are mentioned only when relevant...
