Beschreibung

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.

Application

Reactant for:
Cycloaddition reactions
Ring-expansion reactions of tungsten complexes
N-CN bond cleavage
Retro-Diels-Alder reactions
Regioselective electrochemical α-methoxylation
Synthesis of de-O-chloroacetylation reagents

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