Abstract
The trifunctional P/B/B frustrated Lewis pairs11a–cfeaturing bulky aryl groups at phosphorus [Dmesp (a), Tipp (b), Mes* (c)] were synthesized. Compounds11a,breact with carbon monoxide and form the macrocyclic dimers17a,b, while the carbonylation reaction of the Mes*P/B/B FLP11cgives the macrocyclic trimer18c.
