Lityum tetrametilpiperidid (ko'pincha qisqartiriladi LiTMP yoki LTMP) a kimyoviy birikma bilan molekulyar formula C₉H₁₈LiN. U sifatida ishlatiladi nukleofil bo'lmagan asos bilan solishtirish mumkin LiHMDS xususida pKa va sterik to'siq, yo'q qilish reaktsiyalariga ustunlik berish.

Sintez

U sintezlanadi deprotonatsiya ning 2,2,6,6-tetrametilpiperidin bilan n-butillitiy -78 ° C darajasida. So'nggi hisobotlar shuni ko'rsatadiki, bu reaktsiyani 0 ° C da ham bajarish mumkin.^[1] Murakkab a tarkibida barqaror THF /etilbenzol hal qiluvchi aralashmasi va shu kabi savdo sifatida mavjud.

Tuzilishi

Ko'pgina lityum reagentlar singari u ham a ni hosil qilib, birlashishga moyil tetramer qattiq holatda.^[2]
