  • Patent number: 9126954
    Abstract: To provide: a hydroxy group protecting agent which is stable and easy to use, does not have carcinogenicity, a tearing property or the like, and is inexpensive; and a hydroxy group protection method which enables the protection of a hydroxy group under acidic conditions. [Solution] A hydroxy group protecting agent in which at least one protecting group is bound to a nitrogen-containing electron-withdrawing heterocyclic ring through any one of an oxygen atom, a sulfur atom and a nitrogen atom. The heterocyclic ring is a triazine ring or the like, and the protecting group is a benzyl group or the like. Specifically, the hydroxy group protecting agent is 2,4,6-tribenzyloxy-1,3,5-triazine, 2,4,6-tris(4-methoxybenzyloxy)-1,3,5-triazine or the like. In addition, 2,4,6-tris(t-butoxy)-1,3,5-triazine or the like can also be used. For protecting a hydroxy group, a compound of interest which has a hydroxy group is reacted with the hydroxy group protecting agent under acidic conditions.

  • Patent number: 7635862
    Abstract: Anisotropic conductive adhesive has conductive particles dispersed in adhesive and includes hard particles having conductivity, a resin layer that coats the hard particles and a conductive layer that coats the resin layer. A connection structure electrically connects electrodes to each other with the anisotropic conductive adhesive. A connection method includes the steps of causing the anisotropic conductive to intervene between electrodes, applying pressure to the anisotropic conductive adhesive and allowing the adhesive to be solidified.
