Bis-morpholinophosphorylchloride (Bmpc), in the presence of a base, is an efficient dehydrating agent for both aromatic and aliphatic primary amides, and gives corresponding nitriles under mild conditions in god yields and purity. During the reaction the enantiomeric integrity remains intact.
Azaphthalocyanines with fused triazolo rings: Formation of sterically stressed constitutional isomers
Novakova, Veronika,Roh, Jaroslav,Gela, Petr,Kunes, Jii,Zimcik, Petr
supporting information; experimental part, p. 4326 - 4328 (2012/05/20)
The presented work deals with synthesis and isolation of constitutional isomers of triazolo-fused azaphthalocyanines. Distribution of the isomers did not follow the statistical calculations due to steric effects of the substituents preferring the least sterically stressed C4h isomer.

The dehydration of aldoximes with 2-methylene-1,3-dioxepane (MDO) proceeds smoothly in the presence of a catalytic amount of Lewis acid such as scandium(III) triflate to give corresponding nitriles in moderate to high yields under mild conditions.
On the oxidation of 3-ethylpentane under GifIV and Gif-orsay conditions
Barton, Derek H. R.,Doller, Dario,Ozbalik, Nubar,Balavoine, Gilbert,Gref, Aurore,Boivin, Jean
, p. 353 - 356 (2007/10/02)
The oxidation of 3-ethylpentane under GifIV (and GoAggII) conditions affords, as major product, 3-acetylpentane and not diethylketone as previously reported. The discrepancy is explained by radical chain autoxidation in presence of a weak tertiary C - H bond.
α-ALKYLTHIO-NITRILES VIA CYANATION OF THIO-ACETALS AND KETALS
Reetz, M. T.,Mueller-Starke, H.
, p. 3301 - 3304 (2007/10/02)
The reaction of thio-acetals or ketals with cyanotrimethylsilane in the presence of SnCl4 affords α-alkylthio-nitriles, which can be converted into a variety of other functional groups.
Substituent Effects on the C-C-Bond Strength, 2. The Thermal Stability of Tetrasubstituted Succinonitriles

Rate constants and activation parameters for the thermolysis reaction of ten, partly cyclic tetraalkylsuccinonitriles and of meso-2,3-dimethyl-2,3-diphenylsuccinonitrile were determined.Relationships between ΔG* (300 deg C), ΔH* and ΔS* of the thermolysis reaction on the one hand and the change in strain enthalpy during bond dissociation on the other are pointed out.A force field procedure for the estimation of the strain in α-cyanoalkyl radicals is presented.A quantitative separation of the steric and resonance effects responsible for the thermal dissociation pro cess was achieved successfully.A resonance energy of 5.3 kcal*mol-1 was deduced for tertiary α-cyanoalkyl radicals in agreement with the most recent literature data.
