In cyanation reactions, the cyanide source is often directly added to the reaction mixture, which restricts the choice of conditions. The spatial separation of cyanide release and consumption offers higher flexibility instead. Such a setting was used for the cyanation of iminium ions with a variety of different easy-to-handle HCN sources such as hexacyanoferrate, acetonitrile or α-amino acids. The latter substrates were first converted to their corresponding nitriles through oxidative decarboxylation. While glycine directly furnishes HCN in the oxidation step, the aliphatic nitriles derived from α-substituted amino acids can be further converted into the corresponding cyanohydrins in an oxidative C-H functionalization. Mn(OAc)2 was found to catalyze the efficient release of HCN from these cyanohydrins or from acetone cyanohydrin under acidic conditions and, in combination with the two previous transformations, permits the use of protein biomass as a non-toxic source of HCN.

Page/Page column 3, (2017/12/12)
The present invention relates to processes for preparing for preparing 3-(methylsulfonyl)propionitrile. The processes comprise the steps of first reacting 2-chloroethyl methyl sulfide with sodium cyanide or potassium cyanide in a solvent or a solvent mixture to form 3-(methylthio)propionitrile, and then reacting the isolated 3-(methylthio)propionitrile with acetic anhydride, acetic acid, and hydrogen peroxide to form 3-(methylsulfonyl)propionitrile.

An atom-economic and odorless thia-Michael addition in a deep eutectic solvent
Azizi, Najmedin,Yadollahy, Zahra,Rahimzadeh-Oskooee, Amin
, p. 1722 - 1725 (2014/03/21)
The first 100% atom-efficient and odorless protocol for carbon-sulfur bond formation in a deep eutectic solvent (DES) as both the reaction medium and catalyst is reported. The biodegradable and inexpensive DES provides an efficient and convenient ionic reaction medium for the thia-Michael addition with in situ generation of S-alkylisothiouronium salts in place of thiols without the urea by-product segment. This protocol offers several advantages including short reaction times, high yields, clean reactions, and inexpensive and commercially available starting materials.
Novel atom-economic reaction: Comprehensive utilization of S-alkylisothiouronium salt in the synthesis of thioethers and guanidinium salts
Gao, Pengchao,Leng, Penglin,Sun, Qi,Wang, Xin,Ge, Zemei,Li, Runtao
, p. 17150 - 17155 (2013/09/24)
A novel atom-economic three-component one-pot reaction of a primary amine, an S-alkylisothiouronium salt and a Michael receptor is reported, which affords a guanidinium salt and thioether simultaneously. The guanidine moiety is involved in catalyzing the conjugated Michael addition of the mercaptan. The reaction proceeds under ambient conditions using a non-toxic EtOH-H2O mixture as the solvent, and the two products can be very easily purified. Complete atom economy is achieved by fully utilizing the S-alkylisothiouronium salt and converting the previously wasted mercaptan by-product into the valuable thioether.

Oxidant-free conversion of primary amines to nitriles

supporting information, p. 16352 - 16355 (2013/12/04)
An amide-derived NNN-Ru(II) hydride complex catalyzes oxidant-free, acceptorless, and chemoselective dehydrogenation of primary and secondary amines to the corresponding nitriles and imines with liberation of dihydrogen. The catalyst system tolerates oxidizable functionality and is selective for the dehydrogenation of primary amines (-CH2NH2) in the presence of amines without α-CH hydrogens.
Analysis and anti- helicobacter activity of sulforaphane and related compounds present in Broccoli (Brassica oleracea L.) sprouts
Moon, Joon-Kwan,Kim, Jun-Ran,Ahn, Young-Joon,Shibamoto, Takayuki
experimental part, p. 6672 - 6677 (2011/08/06)
A crude methanol extract prepared from fresh broccoli sprouts was extracted with hexane, chloroform, ethyl acetate, and butanol sequentially. Residual water fraction was obtained from the residual aqueous layer. The greatest inhibition zones (>5 cm) were noted for Helicobacter pylori strain by the chloroform extract, followed by the hexane extract (5.03 cm), the ethyl acetate extract (4.90 cm), the butanol extract (3.10 cm), and the crude methanol extract (2.80 cm), whereas the residual water fraction did not show any inhibition zone. Including sulforaphane, five sulforaphane-related compounds were positively identified in the chloroform extract, of which 5- methylsulfinylpentylnitrile was found in the greatest concentration (475.7 mg/kg of fresh sprouts), followed by sulforaphane (222.6 mg/kg) and 4-methylsulfinylbutylnitrile (63.0 mg/kg). Among 18 sulforaphane and related compounds synthesized (6 amines, 6 isothiocyanates, and 6 nitriles), 2 amines, 6 isothiocyanates, and 1 nitrile exhibited >5 cm inhibitory zones for H. pylori strain. The results indicate that broccoli sprouts can be an excellent food source for medicinal substances.
