I tried finding various articles online for the preparation of 1M solution of sodium tert-butoxide in THF but I got articles relating to the synthesis of potassium tert-butoxide only. I do know that there are companies selling 2M solution of sodium tert-butoxide in THF. I would be grateful if someone could at least send me a link to the article which describes the synthesis process of 1M sodium tert-butoxide in THF.
