Ein neuer Zugang zu Spiroorthocarbonaten und neuen Orthokohlensaeure-Derivaten

Article abstract of DOI:10.1055/s-1990-26845

New and simple processes have been developed, which give in good or excellent yields new diphenoxyalkanediyldioxymethanes, symmetrical and unsymmetrical spiroorthocarbonates, spirocyclic orthothiocarbamic acid esters, and acetals of urea by successive or simultaneous substitution of chloro and phenoxy groups contained in dichlorodiphenoxymethane.
