Procedure
Alternately, the tetrahydro-1,8-dioxa-4a-aza-naphthalene may be functionalized, for example, via reaction of (mono)hydroxy tetrahydro-1,8-dioxa-4a-aza-naphthalene with isocyanate to give urethane tetrahydro-1,8-dioxa-4a-aza-naphthalene, or with diisocyanates, for example, 1,6-hexamethylene diisocyanate, to give diurethane ditetrahydro-1,8-dioxa-4a-aza-naphthalenes, or DESMODUR® 3300 commercially available from Bayer Corporation, Pittsburgh, Pa. which contains multifunctional isocyanates, such as triisocyanate, to give the corresponding multifunctional urethane tetrahydro-1,8-dioxa-4a-aza-naphthalenes. Many of these compounds are novel.
