Research output: Contribution to journalArticlepeer-review


Sundry dipropargyloxy disulfides have been successfully prepared and their rearrangement paths and products have been found to be dependent upon their substitution pattern. Inter alia compounds of two heretofore unknown structure types - 10 and 11 on the one hand and 14 and 15 on the other - have been obtained and characterized.
