Uses

1-Piperidinecarbonitrile was used in the preparation of 1-selenocarbamoylpiperidine.

General Description

1-Piperidinecarbonitrile in tetrahydrofuran (THF) reacts with a solution of piperidyl lithium in THF at 0°C to yield lithium[1,1,3,3-bis(pentamethylene)guanidinate]. It participates in thermal decomposition of the 2H-azaphosphirene metal complexes to yield the Δ3-1,3,2-oxazaphospholene complexes and the Δ3-1,3,2-thiazaphospholene complexes.

Peracid oxidation of an N-hydroxyguanidine compound: A chemical model for the oxidation of N(ω)-hydroxy-L-arginine by nitric oxide synthase

Arginine is oxidized by a class of enzymes called the nitric oxide synthases (NOS) to generate citrulline and, presumably, nitric oxide (·NO). N-Hydroxylation of a guanidinium nitrogen of arginine to generate N- hydroxyarginine (NOHA) has been shown to be a step in the biosynthesis of ·NO. In an effort to elucidate the mechanism by which further oxidation of NOHA occurs, the oxidation of a model N-hydroxyguanidine compound by several peracids was studied in depth. This oxidative chemistry is a possible model for the enzymatic process since the corresponding urea (or citrulline equivalent product) is obtained along with an oxidized nitrogen species. The oxidized nitrogen product was, however, not ·NO but rather HNO. ·NO generation in this chemical system and in the enzymatic process would require another one-electron oxidation. The mechanistic details of this are further discussed.

Electrochemical strategies for: N -cyanation of secondary amines and α C -cyanation of tertiary amines under transition metal-free conditions

Transition metal-free electrochemical approaches for the N-cyanation of secondary amines and the α C-cyanation of tertiary amines have been well established, with products being obtained in moderate to good yields and with good functional group tolerance under ambient conditions. The synthetic application of the protocols has been highlighted through scale-up experiments in a galvanostatic mode. Preliminary mechanistic investigation has confirmed that TBAB played a critical role in N-cyanation transformation and has indicated that the transformation might proceed via a free radical process.

Synthesis of Cyanamides from Cyanogen Bromide under Mild Conditions through N-Cyanation of Allylic Tertiary Amines

Cyanamides were selectively formed through a one-step nucleophilic substitution reaction of allylic tertiary amines with cyanogen bromide. Because of the mild reaction conditions and good yields of the reaction, as well as the commercial availability of the starting materials, this new method represents a valuable tool for the synthesis of cyan-amides through an N-deallylation reaction and an N-cyanation reaction in one pot.

A copper-mediated oxidative N-cyanation reaction

Copper-promoted N-cyanation of aliphatic sec-amine by CuCN is achieved via oxidative coupling. This procedure employs O2 as a clean oxidant. Notably, sulfoximines and 1,1,3,3-tetramethylguanidine also worked well in this procedure. Thus, it represents a key progress in the C-N bond formation reaction as well as in the cyanation reaction.

Iron(III) catalysed synthesis of unsymmetrical di and trisubstituted ureas - A variation of classical Ritter reaction

An application of the classical Ritter reaction for the synthesis of unsymmetrical di and trisubstituted ureas catalyzed by FeCl3 is described. The protocol is of significant interest in view of the easy availability of precursors, mild reaction conditions employed and interestingly its applicability for the alkylation of alcohols capable of forming stable carbocationic intermediates even to the sterically hindered moieties.
