65–70 °C/20 mmHg;3 d 0.827 g cm?3. | [Uses]
(Trimethylsilyl)acetonitrile has been used in catalytic cyanomethylation of various carbonyl compounds in the presence of Lewis bases. | [Uses]
α-carbanion is a useful alternative to LiCH2CN for nucleophilic
cyanomethylation; (Z)-selective Peterson alkenation). Trimethylsilylacetonitrile participates in the following synthesis reactions: Metalation, Peterson Alkenation (Cyanomethylenation), Michael Addition, Reactions with Other Electrophiles, Cyanomethylation, Metal-Catalyzed Reactions etc. | [Preparation]
From chlorotrimethylsilane, zinc, and
XCH2CN, (X = Cl, 61% yield; X = Br, 81% yield). | [Purification Methods]
Check if NMR and IR spectra show impurities; if present dissolve it in *C6H6 (10volumes), wash it with buffer (AcOH/AcONa pH ca 7) several times, dry (CaCl2) it, evaporate and distil it. IR: (CCl4) 2215 (CN) cm-1, NMR (CCl4): 0.23 (s, 9H, SiMe3), and 1.53 (s, 2H, CH2CN). [Matsuda et al. J Chem Soc, Perkin Trans 1 26 1979, Beilstein 4 IV 3974.] |
