헥사플루오로프로판올기(-C(CF3)2OH, HFIP기) 함유 방향족 알콕시실란(4)를, 저렴한 출발 원료로부터, 높은 반응 변환율과 선택률로 제조하는 방법을 제공한다. 당해 제조 방법은, 하기와 같이, 방향족 할로실란(1)을 루이스산의 존재 하에서 헥사플루오로아세톤과 반응시켜, HFIP기 함유 방향족 할로실란(2)를 얻는 제 1 공정과, 당해 HFIP기 함유 방향족 할로실란(2)를 알코올과 반응시켜, HFIP기 함유 방향족 알콕시실란(4)를 얻는 제 2 공정을 포함한다. [화학식 68] TIFFpct00070.tif35165 Provided is a method for producing an aromatic alkoxy silane (4) containing a hexafluoropropanol group (-C(CF3)2OH, HFIP group) from an inexpensive starting material at a high reaction conversion rate and high selectivity. This production method includes: a first step for obtaining an HFIP group-containing aromatic halosilane (2) by reacting an aromatic halosilane (1) with hexafluoroacetone in the presence of a Lewis acid; and a second step for obtaining an HFIP group-containing aromatic alkoxysilane (4) by reacting the HFIP group-containing aromatic halosilane (2) with an alcohol.
