Спасибо!
Вот, например, типичная схема получения макроинициаторов полимеризации с концевыми OH-группами: (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3671801/). И реакция идет в присутствии триэтиламина (зачем ?):
In a two-neck round-bottom flask, PF127 (12.6 g, 1 mmol) was dissolved in 20 mL dichloromethane at room temperature. The solution was cooled to 0°C and triethylamine (0.7 mL, 5 mmol) was added with stirring. After 20 minutes, 2-bromo-2-methylpropionyl bromide (0.6 mL, 5 mmol) was slowly injected into the reaction flask under argon. After 48 hours reaction at room temperature, the bromide-modified product, di-2-bromoisobutyryl-pluronic F127 (PF127-Br), was obtained by precipitation in excess n-hexane and dried under vacuum.
