HCID 19435776Zinc pivalate

Procedure

The 3-(trifluormethyl)phenylzinc pivalate (1d) product can be stored under inert gas atmosphere at ambient temperature for one week without any loss of activity (entry 1, Table 1 below). After 5 minutes of storage in air, 95% of active zinc species could be determined by titration (Table 1, entry 2). After 15 minutes, the activity is reduced to 58% (Table 1, entry 3) and after 30 and 45 minutes, activities of 43% and 40% are obtained (Table 1, entries 4-5). After storage on air for 60 minutes, active zinc species cannot be detected (Table 1, entry 6).

Workup

  1. customafter 30 and 45 minutes, activities of 43% and 40% are obtained (Table 1, entries 4-5)
