5-ortho-Carboranylsalicylaldehyde was prepared from 5-iodosalicylaldehyde in six steps in 18% overall yield, and also from 5-iodosalicylic acid in seven steps in 45% overall yield. The reaction of 5-ortho-carboranylsalicylaldehyde with Fischer's base gave a spiropyran in 63% yield.

Catalytic partnership: A photochemical dual-catalytic cross-coupling to form alkynyl sulfides through C(sp)−S bond formation is promoted by a carbazole-based photocatalyst using continuous flow techniques in short reaction times (50–96 %, 30 min). In addition, incorporation of an alkynyl sulfide functional group into a macrocyclic scaffold was demonstrated as the first application of photoredox/nickel
