Abstract
A set of novel, easily synthesized aluminum complexes, Al[κ2-N,N-2-(methylamino)pyridine]2R (R = Et, iBu) are reported. When subjected to 1 atm of CO2 pressure, each hemilabile pyridine arm dissociates and facilitates cooperative activation of the CO2 substrate reminiscent of a Frustrated Lewis Pair. This reaction has limited precedent for Al/N based Lewis Pair systems, and this is the first system readily shown to sequester multiple equivalents of CO2 per aluminum center. The ethyl variant then reacts further, inserting a third equivalent of CO2 into the aluminum alkyl to generate an aluminum carboxylate. Examples of this type of reactivity are rare under thermal conditions. A joint experimental/computational study supports the proposed reaction mechanism.

Abstract
The alternating copolymerization of CO2/epoxides is a useful means to incorporate high levels of carbon dioxide into polymers. The reaction is generally proposed to occur by bimetallic or bicomponent pathways. Here, the first indium catalysts are presented, which are proposed to operate by a distinct mononuclear pathway. The most active and selective catalysts are phosphasalen complexes, which feature ligands comprising two iminophosphoranes linked to sterically hindered ortho-phenolates. The catalysts are active at 1 bar pressure of carbon dioxide and are most effective without any cocatalyst. They show low-pressure activity (1 bar pressure) and yield polymer with high carbonate linkage selectivity (>99%) and isoselectivity ( Pm > 70%). Using these complexes, it is also possible to isolate and characterize key catalytic intermediates, including the propagating indium alkoxide and carbonate complexes that are rarely studied. The catalysts are mononuclear under polymerization conditions, and the key intermediates show different coordination geometries: the alkoxide complex is pentacoordinate, while the carbonate is hexacoordinate. Kinetic analyses reveal a first-order dependence on catalyst concentration and are zero-order in carbon dioxide pressure; these findings together with in situ spectroscopic studies underpin the mononuclear pathway. More generally, this research highlights the future opportunity for other homogeneous catalysts, featuring larger ionic radius metals and new ligands, to operate by mononuclear mechanisms.

Abstract
CO(2) inserts into the Sm-S and Sm-Se bonds of [(C(5)Me(5))(2)Sm(mu-EPh)](2) (E = S, Se) to form the first crystallographically characterized (O(2)CEPh)(1-) complexes, [(C(5)Me(5))(2)Sm(mu-O(2)CEPh)](2). These complexes are structurally analogous to [(C(5)Me(5))(2)Sm(mu-O(2)CR)](2) complexes, but they are less soluble. This feature was utilized in the reaction of Me(2)AlCl with [(C(5)Me(5))(2)Sm(mu-O(2)CEPh)](2), which forms crystallographically characterizable [Me(2)Al(mu-O(2)CEPh)](2) complexes. Such complexes could not be isolated from an analogous carboxylate reaction. [(C(5)Me(5))(2)Sm(mu-O(2)CSePh)](2) decarboxylates in THF to form (C(5)Me(5))(2)Sm(SePh)(THF). The loss of CO(2) rather than COSe with formation of (C(5)Me(5))(2)Sm(OPh)(THF) was established by (13)CO(2) studies and independent synthesis of (C(5)Me(5))(2)Sm(OPh)(THF) from (C(5)Me(5))(2)Sm[N(SiMe(3))(2)] and PhOH.
