Transformation of CO2 and isocyanates mediated by N-borane-substituted cyclic phosphine imides (BCPIs) via λ5-oxazaphosphetanes†
We herein report reliable evidence that λ5-oxazaphosphetane species are a key intermediate in the transformation of CO2 and isocyanates through their reaction with N-borane-substituted cyclic phosphine imides (BCPIs). We have isolated and fully characterized several λ5-oxazaphosphetane species prepared via formal [2 + 2] cycloaddition reactions between BCPIs and CO2 or isocyanates. The transformation of these λ5-oxazaphosphetanes via retro-ring opening reaction afforded an isocyanate and a carbodiimide from the CO2- and isocyanate-derived λ5-oxazaphosphetanes.
