| DI-TERT-BUTYL ACETYLENEDICARBOXYLATE Usage And Synthesis |
| General Description | The cross-cyclotrimerization of di-tert-butyl acetylenedicarboxylate, silylacetylenes and acrylamides was studied with cationic rhodium(I)/(R)-tol-binap complex as catalyst. Glycosyl azides were subjected to 1,3-dipolar cycloaddition with di-tert-butyl acetylenedicarboxylate. |
