    摘要: An objective of this invention is to provide an epoxy resin composition for encapsulating a semiconductor chip, which is excellent in flowability and moldability without deterioration in crack resistance during soldering and flame retardance. Specifically, this invention provides a resin composition for encapsulating a semiconductor chip comprises an epoxy resin (A) containing the specific structure; a phenolic resin (B) containing the specific structure; an inorganic filler (C); a curing accelerator (D); a silane coupling agent (E); and Compound (F) containing an aromatic ring in which at least two adjacent carbon atoms of the ring member carbon atoms are coupled to a hydroxyl group, respectively.

    摘要: Processes for preparing sulfoxides useful as drugs such as acid secretion inhibitors or antiulcer drugs or intermediates for the preparation of drugs in high yields, at high purities, and with safety. Specifically, a process for the preparation of sulfoxides (II) by oxidizing a thio ether (I) with a peroxoborate salt in the presence of an acid anhydride or a metal catalyst; and a process for the preparation of sulfoxides (II) by oxidizing a thio ether (I) with an N-halosuccinimide, 1,3-dihalo-5,5-dimethyl-hydantoin or dichloroisocyanuric acid salt in the presence of a base. In said formulae R1 is hydrogen, methoxy or difluoromethoxy; R2 is methyl or methoxy; R3 is 3-methoxypropoxy, methoxy or 2,2,2-trifluoroethoxy; and R4 is hydrogen or methyl
