✦ Synopsis

A recent well-smplified publication1 reports the synthesis of new classes of aromatic compounds having the general structure I (M = Ge or Si). These were claimed to be heterocyclic analogs of tha cyclopropenyl cation2 (II) and their aromatic charact:r was ascribed to p Worbital interaction of the double bond with an empty d-orbital of the heteroatom, rather than the purely psorbital interactions in II.

However, three discrepancies, listed below, which appeared in the Russian paper led us to reinvestigate the nature of the products.

a) The "aromatic character" of the synthesized products was based on the stability of the systems to the action of bromine, alkali, and strong acids and lack of hydrogen addition in a catalytic process.
