Oligosiloxanes can be obtained in a single flask in a programmed fashion. In their Communication on page 3168 ff., S. Shimada and co‐workers report a novel oligosiloxane synthesis consisting of three successive reactions in one pot: iridium‐catalyzed hydrosilylation, boron‐catalyzed rearrangement, and boron‐catalyzed cross‐coupling. The sequence of SiR 2 units in the oligosiloxane product can be controlled by simply changing the order of hydrosilane addition.
