2,2,6,6-Tetramethyl-3,5-heptanedionato lithium, (Li(TMHD)) - Introduction
(2,2,6,6-Tetramethyl-3,5-heptanedionato)lithium ((2,2,6,6-Tetramethyl-3,5-heptanedionato)lithium) is an organolithium compound. The following is a description of its nature, use, formulation and safety information:
Nature:
(2,2,6,6-Tetramethyl-3,5-heptanedionato)lithium is a colorless to pale yellow solid, soluble in non-polar organic solvents such as ether and kerosene. It is stable in air, but hydrolyzes when deliquesced or in contact with water.
Use:
(2,2,6,6-Tetramethyl-3,5-heptanedionato)lithium is mainly used as a precursor of organolithium compounds for the preparation of other organolithium compounds. It can also be used as a catalyst for the synthesis of catalysts and organic synthesis reactions.
Preparation Method:
The preparation of (2,2,6,6-Tetramethyl-3,5-heptanedionato)lithium is generally obtained by reacting (2,2, 6,6-tetramethyl -3,5-heptanedione) with lithium chloride or lithium carbonate. The reaction process is usually carried out under an inert atmosphere and the reaction is controlled at a relatively low temperature.
Safety Information:
(2,2,6,6-Tetramethyl-3,5-heptanedionato)lithium irritant to skin and eyes. During handling and use, appropriate safety measures should be taken, such as wearing protective gloves and eye/face protection. If you accidentally spill or come into contact with skin or eyes, rinse immediately with water and seek medical help. In addition, chemicals should be stored in a dry, well-ventilated place, away from ignition and oxidizing agents.
