PROBLEM TO BE SOLVED: To provide a precursor for synthesis of a compound containing a difluorooxymethylene bridge. SOLUTION: The aldehyde containing a difluorooxymethylene bridge is expressed by general formula: OHC-(A<SP>11</SP>)<SB>m</SB>-Z<SP>11</SP>-(A<SP>12</SP>-Z<SP>12</SP>)<SB>n</SB>-(A<SP>13</SP>-Z<SP>13</SP>)<SB>p</SB>-A<SP>14</SP>. Wherein Z<SP>11</SP>, Z<SP>12</SP>or Z<SP>13</SP>are each a -CF<SB>2</SB>O-, etc., and m, n or p are each 0 or 1. COPYRIGHT: (C)2005,JPO&NCIPI
