A facile synthesis of fluorinated alkoxytrimethylsilanes using 1-methylimidazole as an acid scavenger
摘要:
Fluorinated alkoxytrimethylsilanes (R1CH2OSiMe3), potential candidates for the third-generation cleaning agents, were synthesized in high yields over 95% from the reaction of chlorotrimethylsilane and fluorinated alcohol (R1CH2OH) in the presence of 1-methylimidazole. Elemental and H-1 NMR spectroscopic analysis showed that the reaction proceeds through the formation of an intermediate, 3-methyl-1-trimethylsilylimidazolium chloride. (c) 2006 Elsevier B.V.
