Several catalysts for converting CO2 into cyclic carbonates at room temperature and 1 bar CO2, have been reported. In particular, aluminum, the most abundant metal in the earth’s crust (the metals are in the order Al, Fe, Ca, Na, K, Mg, and Ti), is a very attractive metal for this study due to its low cost, low toxicity and high Lewis acidity. However, only a few examples of efficient non–toxic catalysts with aluminum metal centers capable of operating at ambient temperature and 1 bar CO2 are known. Typically, non–toxic Al–based catalysts require catalyst loading (> 2.5 mol%) and a long reaction time (24 h) to reach a high conversion to styrene carbonate under ambient conditions. Their catalytic activities are in the range of TON = 8.4–39.2 and TOF = 0.63–3.73 h–1. Thus, the development of new, more active Al–based catalytic systems that allow lower catalyst loading (< 1.0 mol%) and a high TON (> 100) under ambient conditions is needed. The detailed synthesis, characterization, and catalytic activities at ambient conditions of new dimeric aluminum catalysts will be discussed.
