Synthesis of Thiophenedicarbonyldiazides and Di-t-butyl Thiophendicarbamates

Dicarbamates 1b and 1c, and dicarbonyldiazides 2b and 2c are obtained in good yields starting from thiophenedicarboxylic acids 3b and 3c, but the vicinal diacids 3a and 3d are not suitable for the synthesis of dicarbamates 1a and 1d and dicarbonyldiazides 2a and 2d; 1a is prepared by a stepway procedure previously described, and 1d by t-butoxycarbonylation of the recently known 3,4-thiophenediamine.
