Disclosed is a low cost, efficient method for production of a salt composed of an arylsulfonium and a fluorinated alkylfluorophosphate which method does not required a large excess amount of acid. The method comprises reacting an aryl compound Ar-H and with a compound represented by the formula (I),
wherein R1 and R2 denote a hydrocarbon group or a heterocycle group which may be substituted, or they are bonded with each other directly or via -O-, -S-, -SO-, -SO2-, -NH-, -NR' -, -CO-, -COO-, -CONH-, an alkylene group having 1 to 3 carbon atoms or a phenylene group to form a ring structure which may be substituted, wherein R' denotes a C1-5 alkyl group or a C6-10 aryl group; in the presence of an acid represented by the formula (2), wherein Rf denotes an alkyl group 80 % or more of whose hydrogen atoms are substituted by fluorine atoms, "a" is an integer of 1 to 5; and a dehydrating agent to produce the salt of sulfonium represented by the formula (3).
本发明公开了一种生产由芳基锍和氟化烷基氟磷酸盐组成的盐的低成本、高效率方法,该方法不需要大量过量的酸。该方法包括使芳基化合物 Ar-H 与式 (I) 所代表的化合物反应、
其中 R1 和 R2 表示可被取代的烃基或杂环基,或者它们直接或通过 -O-、-S-、-SO-、-SO2-、-NH-、-NR'-、-CO-、-COO-、-CONH-、具有 1 至 3 个碳原子的亚烷基或亚苯基相互键合以形成可被取代的环结构,其中 R' 表示 C1-5 烷基或 C6-10 芳基;在式 (2) 所示的酸存在下,其中 Rf 表示烷基,其 80% 或更多的氢原子被氟原子取代,"a "为 1 至 5 的整数;以及脱水剂,以生成式 (3) 所示的锍盐。
