The reactions of CO 2 with as eries of phosphinoboranes, including R 2 PBpin (R = Ph, tBu;p in = pinacol), R 2 PBMes 2 (R = Ph, tBu;M es = 2,4,6-Me 3 -C 6 H 2 ), and R 2 PBcat (R = Ph, tBu, Mes;c at = catechol)a re described. Although R 2 PBpina nd R 2 PBMes 2 afford products of the form R 2 PCO 2 Bpin (R = Ph 1, tBu 4)a nd R 2 PCO 2 BMes 2 (R = Ph 2, tBu 3), respectively,R 2 PBcat lead to further reactionaffording the diphospha-ureas, (R 2 P) 2 CO (R = Ph 5, tBu 6,M es 7), together with O(Bcat) 2 .C omputational studiesp rovide insight into the mechanism, revealing an intermediate derived from double phosphinoboration of CO 2 .[a] J.Supporting information and the ORCID identification number(s) for the author(s) of this articlecan be found under: https://doi.org/10.

S), were synthesized and characterized by FT-IR spectroscopy, TG-DSC, and singlecrystal and powder X-ray diffraction analysis. The single-crystal X-ray diffraction data revealed that 1 and 2 are discrete structures, whereas 3 is a polymer. In 1 and 2, Ca 2+ is seven-coordinate and forms a monocapped trigonal prism. In 1, the prisms are pairwise connected with the assistance of two [μ 2 -HTBA-O,O′] − ligands. In 3, Sr 2+ is coordinated by four monodentate HTBA − via S or O donors and four waters, with the formation of a distorted square antiprism. The antiprisms are connected by μ 2 -O,S bridging HTBA − . Hydrogen bonding involving coordinated water and π-π interactions plays an important role in construction of the supramolecular 3-D structures in 1-3. Infrared spectroscopic data supported the structural data. The thermal stability of 1-3 decreases in the order 1 > 2 > 3. Dehydration of 1-3 was a multi-step process, followed by exothermic oxidative degradation of the 2-thiobarbiturate moiety between 290 and 800°C.

“…[9,10] Reactions of CO 2 with main-group metal amides were also reported. [11] We recently developed a new approach to main-group reactivity, derived from the concept of "frustrated Lewis pairs", [12] that is, systems in which steric congestion precludes neutralization. These systems offer latent Lewis acidity and basicity for reaction with small molecules.…”
