carboxy‐, amino‐ and nitro‐substituted thiols could be added to 1 with few by‐products in 16–90 % yield. Oxidation of the products allows tuning of the polarity and subsequent reactions of the products. The click‐type reaction proceeds even faster with selenols, as was shown in a proof of concept. Thiol addition to 1 offers a facile tool for surface modification, conjugation and tuning of hydrophilicity in
