Lithium Hexamethyldisilazide (LHMDS) Albemarle

LiHMDS is often used in organic chemistry as a strong non-nucleophilic base. Its conjugate acid has a pKa of ~26, making it is less basic than other lithium bases, such as LDA (pKa of conjugate acid ~36), but it is more sterically hindered and hence less nucleophilic. It can be used to form various organolithium compounds, including acetylides or lithium enolates. NettetInfobox references. Potassium bis (trimethylsilyl)amide (commonly abbreviated as KHMDS, Potassium ( K) H exa M ethyl D i S ilazide) or potassium hexamethyldisilazane [1] is the chemical compound with the formula ( (CH 3) 3 Si) 2 NK. It is a strong, non-nucleophilic base with an approximate pK a of 26 (compare to lithium diisopropylamide, … NettetInfobox references. Lithium diisopropylamide (commonly abbreviated LDA) is a chemical compound with the molecular formula LiN (CH (CH3)2)2. It is used as a strong base and has been widely utilized due to its good solubility in non-polar organic solvents and non-nucleophilic nature. cheapest flights to orlando from chicago
