Abstract
Fluoroalcohol compounds of formula (4) are prepared by reacting a fluorine compound of formula (1) with reducing agents or organometallic reagents of formulas (2) and (3) wherein Ris H or a monovalent C-Chydrocarbon group in which any —CH— moiety may be replaced by —O— or —C(═O)—, Ris H or a monovalent C-Chydrocarbon group, Rand Rare H or a monovalent C-Chydrocarbon group, and Mis Li, Na, K, Mg, Zn, Al, B, or Si. From the fluoroalcohol compounds, fluorinated monomers can be produced in a simple and economic way, which are useful in producing polymers for the formulation of radiation-sensitive resist compositions.
