Conclusions

  1. 1.

    Metallation of diacetals of 5-substituted-2-alkylthio-3-thiophenecarboxaldehydes with butyllithium in ether proceeds at the freeβ-position of the thiophene ring, so that different polyfunctional derivatives of thiophene can be synthesized.

  2. 2.

    By the action of sodium in liquid ammonia on 5-methoxy-2-methylthio-3-thiophenecarboxaldehyde diethylacetal, and subsequent treatment with water, 5-methylthieno [3,2-d]isothiazole is formed.

  3. 3.

    Certain intracoordination compounds of Co(II), Ni(II), and Zn were obtained which include the thiophene ring substituted in the α-position with a methoxy group.
