1-Chlorocarbonyl-4-piperidinopiperidine - Introduction
Nature:
[1,4 '] Bipiperidine -1'-carboxylic acid chloride is a colorless or pale yellow liquid with a pungent odor. It has a high vapor pressure and solubility, and can be dissolved in a variety of organic solvents, such as ethanol, methanol and ether. It is a strongly acidic compound that reacts with bases to produce salts.
Use:
[1,4 '] Bipiperidine -1'-carbonyl chloride is commonly used as an intermediate in organic synthesis. It can be used to synthesize compounds such as pesticides, pharmaceuticals and dyes. In addition, it can also be used for acylation, acyl chlorination and acyl substitution in organic synthesis reactions.
Preparation Method:
The preparation of [1,4 '] bipiperidine -1'-carboxylic acid chloride is generally achieved by acylation of bipiperidine -1-amine. A common method is to use anhydrous formic acid as the acylating agent and to add an acidic catalyst, such as hydrochloric acid or sulfuric acid. The reaction is typically carried out at low temperature to yield [1,4 '] bipiperidine -1'-carboxylic acid chloride.
Safety Information:
Because [1,4 '] bipiperidine -1'-carbonyl chloride is irritating and corrosive, it is necessary to take appropriate safety measures during operation. Wear suitable protective gloves, goggles and protective clothing. Avoid contact with skin, eyes and respiratory tract. Operate in a well-ventilated area and avoid contact with combustibles.
