Methyl azelaaldehydate, soy nitriles, and oleonitrile were compared as starting materials for making nylon-9. Less difficulty was encountered in purifying intermediates from oleonitrile than from the other two. All 3 routes involved hydrolysis of methyl 9-aminononanoate to 9-aminononanoic acid. Self catalyzed hydrolysis of the amino ester in water produced low yields of monomer owing to oligome...

The synthesis of organic nitriles without using toxic cyanides is in great demand but challenging to make. Here we report an environmentally benign and cost-efficient synthesis of nitriles from the direct oxidative cyanation of primary carbon-hydrogen bonds with easily available molecular oxygen and urea. The key to this success is to design and synthesize manganese oxide catalysts fixed inside...

A micellar electrokinetic capillary chromatography (MECC) method has been developed for monitoring the myrosinase catalysed hydrolysis of 2-hydroxy substituted glucosinolates and the simultaneous formation of the corresponding degradation products (oxazolidine-2-thiones (OZTs) and nitriles). Glucosibarin ((2R)-2-hydroxy-2-phenylethylglucosinolate) was chosen as the model glucosinolate owing to ...

Microwave assisted CpCo(CO)(2) catalyzed cross-cyclotrimerizations of 1,7,9,15-hexadecatetrayne with two different nitriles to give unsymmetrically substituted bis(tetrahydroisoquinolines) was studied. The reaction proceeded with a range of alkyl and aryl nitriles with reasonable isolated yields.

We reveal here the unique reactivity of α-(alkylideneamino)nitriles toward molecular oxygen. Thus, α-(alkylideneamino)nitriles can serve as the imide building block for the efficient synthesis of imides in the absence of transition metals under extremely mild conditions.

A palladium-catalyzed desulfitative cyanation of arenesulfonyl chlorides and sodium sulfinates has been developed, providing aryl nitriles in moderate to excellent yields. It represents a facile procedure to access aryl nitriles.

The three title reductant systems have significant advantages in generating aldehydes from nitriles. These include: the utilization of convenient hydrogen sources, namely, sodium hypophosphite monohydrate and formic acid, respectively, and of the relatively inexpensive Raney nickel and Raney (Ni/Al) alloy; the convenience of conducting the reaction(s) in aqueous media at ambient temperatures an...
