DIPHENYL DITELLURIDE - Introduction
diphenyl ditelluride, also known as diphenylditellurium with the chemical formula (C6H5) 2te2, is an organotellurium compound. The following is a description of the nature, use, preparation and safety information of diphenyl ditelluride:
Nature:
-Appearance: diphenyl ditelluride in colorless crystal or yellow powder
-Melting point: About 200 ° C
-Boiling point: About 430-440 ° C
-Solubility: Insoluble in water, soluble in organic solvents such as ethanol and chloroform.
Use:
-Catalyst: diphenyl ditelluride can be used as a ligand of transition metal catalyst and play a catalytic role in organic synthesis reactions. For example, it can catalyze decarbonylation reactions, alkylation reactions, and the like.
-Antioxidant: diphenyl ditelluride has antioxidant properties and can be used as an anti-aging agent for rubber, plastic and other materials.
-Other applications: diphenyl ditelluride is also used in electrochemical research, preparation of photoelectric materials, etc.
Method:
diphenyl ditelluride can be obtained by the reaction of phenyl lithium with strontium Telluride. The specific preparation method is as follows:
1. Under an inert atmosphere, the phenyl lithium is reacted with strontium tritelluride at ambient temperature.
2. The product was obtained by cooling crystallization.
Safety Information:
