Bolton, Roger published the artcileSulfuryl chloride as an electrophile. IV. Steric hindrance to activation by the methoxy-group, Category: ethers-buliding-blocks, the publication is Journal of the Chemical Society [Section] B: Physical Organic (1970), 1770-2, database is CAplus.
The rates of reactions of sulfuryl chloride with a number of aromatic ethers have been studied in chlorobenzene solution The additivity principle, which holds in a number of examples of this reactions, fails when 2 substituents are placed ortho to the methoxyl group in anisole. 2,3,4,6-Tetramethylanisole substitutes Cl at a similar rate to that of 3-methylanisole, its calculated rate coefficient being 2000 times the exptl. value. Neither increasing the size of the alkyl group attached to the O atom nor using only 1 ortho substituent brought about any detectable effect due to steric factors.
