Abstract
A method for producing a silicon compound containing an iodophenyl group, including substituting iodine for a trialkylsilyl ((R)Si) group bonded to a phenyl group by using an iodine-containing electrophilic reagent (I-X) as shown by the following reaction equation: where all of R's may be identical to or different from each other and each represent an alkyl group having 1 to 6 carbon atoms; Rrepresents a single bond or a divalent organic group; Rrepresents an organic group having 1 to 10 carbon atoms; Rrepresents an organic group having 1 to 10 carbon atoms; R represents an organic group having 1 to 6 carbon atoms; n0 is 1, 2, or 3, n1 is 1, 2, or 3, n2 is 0, 1, or 2, and n3 is 0, 1, or 2, provided that 1≤n1+n3≤3; and X represents a counter substituent of iodine, acting as an electrophilic reactive species.
