Abstract / Bemerkung
The two oxygen-bridged geminal Frustrated Lewis Pairs (FLP) tBu2P-O-AlBis2 (Bis = CH(SiMe3)2, 1) and tBu2P-O-Si(C2F5)3 (2) were reacted with the heterocumulenes PhNCO, PhOCN, PhNCS, CS2 and PhNSO as well as SO2. With isocyanate and cyanate, both 1 and 2, form addition products under formation of five-membered rings. With CS2, isothiocyanate and sulfinylaniline only 1 forms stable adducts, while 2 shows reactivity towards sulfinylaniline but the product decomposed after several minutes. The reaction of 1 with SO2 led to a partial cleavage of the P-O-Al and Al-C units, confirmed by X-ray diffraction studies of a complex aggregate. The reaction of 2 with SO2 affords the 1,2-addition product. All adducts were characterized by means of multinuclear NMR spectroscopy, X-ray crystallography and CHN analyses. © 2023 Wiley-VCH GmbH.
