A proton is the weakest electrophile. For example, anhydrous HF does not add to tetrafluoroethylene at ambient temperature or to hexafluoropropene, even at 200°C [6]. Arsenic trifluoride in the presence of SbF5 (this mixture is a source of the F2As+ cation [42,43]) reacts with tetrafluoroethylene at 20 °C to form a mixture of F-(diethyl)-(4) and F-(triethyl)(5) arsines ... 

Explosive reaction with alkenes + diiodomethane, sulfur dioxide. Reacts violently with bromine, water, nitro compounds. Ignites on contact with air, ozone, methanol, or hydrazine. Reacts violently with nonmetal halides (e.g., arsenic trichloride or phosphorus trichloride) to produce pyrophoric triethyl arsine or triethyl phosphine. To fight fire, do not use water, foam, or halogenated extinguishing agents. Use dty materials, such as graphite, sand, etc. When heated to decomposition it emits toxic fumes of ZnO. See also ZINC COMPOUNDS. 

The insoluble alkynylsilver complexes are regarded as coordination polymers (RC=CAg)co with cross-linking between the metal atoms and the ethynyls of adjacent RC=CAg units. Donor molecules (L) such as tertiary amines, phosphines and arsines can partly break down the polymeric structure. Thus the reactions of PhC=CAg with isopropylamine, trimethyl-, triethyl- or triphenylphosphine and triethylarsine yield the 1 1 complexes of the composition [(L)AgC=CR]49-51. 

Violent reactions can occur with halogens, halogenated hydrocarbons, nitroorganics, oxidizers, sulfur dioxide, and chlorides of phosphorus, arsenic, and antimony. With the latter compounds, diethylzinc forms pyrophoric triethylphosphine, triethyl arsine, and triethylstibine, respectively. 

Chemical vapor deposition (CVD) occurs when molecules from a moderate density gas condense on a surface and react to form a solid. The reaction also creates product molecules that are released into the gas phase. Moderate gas density usually means > 0.1 Pa. The general features of the process are shown schematically in Figure 12.1. A (simplified) typical CVD reaction for formation of GaAs by reaction of arsine (AsHj) with triethyl gallium [Ga(C2H5)3] might be ...
