Table 3. Products of the reaction of phosphor-nitrilic chloride with amines.

Phosphorus nitrile chloride forms adduct (10) with DMF in the ratio 1 4, which is useful for the preparation of formamidines and azavinylogous formamidinium salts. It is supposed that the dehydration of primary amides to nitriles with (PNChls as well as the formation of 2-alkylbenzothiazoles from 2-(methylthio)anilides and (PNChls in the presence of triethylamine proceed via similar adducts." ... 

Many other (cross-) metathesis reactions of functionalized olefins have been shown to be possible in the presence of rhenium-based catalysts, such as self-metathesis (or cross-metathesis with normal olefins) of allyl- and vinylsilanes, unsaturated nitriles, chlorides, bromides etc. The products of these reactions are not yet of use in fine chemistry, but this might be remedied by future developments in this area. 

Naked cyanide ion. Alkyl halides are converted into nitriles by potassium cyanide in the presence of a catalytic amount of 18-crown-6. Acetonitrile (or benzene) is used as solvent, and the two-phase system is stirred vigorously at 25-83°. Little or no reaction occurs in the absence of the crown ether, an indication that the ether is functioning also as a phase-transfer catalyst. Primary halides are also converted quantitatively into nitriles chlorides react much faster than bromides. A few percent of elimination products are formed in the reaction of secondary halides. Cyclohexyl halides give only cyclohexene by elimination. o-Dichlorobenzene fails to react. Methacrylonitrile undergoes hydrocyanation to 1,2-dicyanopropane (92% yield). 

At present, heat shield materials consist of poly(tetrafluorethylene), Si02-filled reinforced phenolic resins, or Si02-filled epoxide/polyamide combinations. Development-stage materials are polyimides, silicones, phosphor nitrilic chlorides, and polyboron phosphorus compounds. 

Silicone oils (product may be diluted by hydrocarbons, ethers, ketones or chlorohydrocarbons, although this does not, however, appear as a specific claim) Aluminium oxides, titanium dioxides, plus various silicas. These react with silicone oil in situ, with the reaction being catalyzed by an acid-condensation reagent (1) Dimethyl polysiloxane -1-silica -t- aerogel -t- AICI3 diluted by toluene. (2) Dimethyl polysiloxane -1-alumina -t- SnCU diluted by toluene. (3) Dimethyl polysiloxane -1-precipitated silica -1-phosphorous nitrile chloride + poly(ethylene glycol) stearate 1-30...

At room temperature the Sml2-H20 system rapidly reduces carboxylic acids, esters, amides, nitriles, chlorides, alkenes, nitro compounds and heteroaromatic rings [90]. Some examples are reported in Table 6.12.
