The present invention provides a photocurable composition which contains a photobase generator capable of generating a satisfactory amount of a base in a high quantum yield when irradiated even with a small quantity of light for a short time, and contains a curable compound that is rapidly cured by the generated base such that the composition is cured into a cured product. The photocurable composition comprises: a photobase generator (A) which is a salt of a carboxylic acid (a1-1) represented by the following formula (1-1) with a basic compound (a2), and a curable compound (B) which has, in one molecule thereof, at least two functional groups selected from among epoxy group, (meth)acryloyl group, isocyanato group, acid anhydride group, and alkoxysilyl group,
where R1 to R7 in the above formula (1-1) each are hydrogen or an organic group, R1 to R7 may be the same or different, and two of R1 to R7 may be bonded to each other to form a ring structure.

A general approach to fluorinated (hetero)aromatic derivatives is elaborated. The key reaction is a deoxofluorination of substituted acetophenones with sulfur tetrafluoride (SF4). In contrast to previous deoxofluorination methods, this transformation is fast, scalable (up to 70 g), and high-yielding. More than 100 novel or previously hardly accessible fluorinated heterocycles, interesting for medicinal
