The reactions of spirophosphoranes containing a PH bond with aldehydes, imines, and animals lead to spirophosphoranes (10–10) containing a PC bond, while with acid chlorides, β-functional phosphiates are formed (compounds 35–38). Dependeing on the nature of the heteroatom attached to phosphorus, the reaction of spirophosphoranes with phenyl isocyanate gives a spirophosphorane (YHOH, compounds 31

The utility of the 2-(arylcarbamoyloxy)ethylgroup for protection of internucleosidic phosphate linkages in oligonucleotide synthesis was studied. Of the three protecting groups tested, the 2-[(1-naphthyl)carbamoyloxy]ethyl demonstrated high coupling yields, favorable deprotection kinetics and the highest hydrolytic stability of the thymidine phosphoramidite building block. The mechanism of deprotection

worldwide. Chemical recycling represents a promising strategy by converting waste polymers into valuable monomers, fuels or chemicals. However, due to multi-component features and similar chemical activities, the chemical recycling of major polymer components often comes at the expense of minor polymer components. Herein, starting from ubiquitous textiles, the effect of spandex on the chemical recycling
