Reactions of Hexa-tert-bbtylcycolotrigermane: Isolation of an Enantiomerically Pure 1,3-Diiodotrigermane

摘要

The hexaarylcyclotngermar.es 1. which have been known since 1982, can he photochemically and thermally converted to ketraaryldigermenes (tetraaryldigermaethenes) 2. These, in turn, undergo a large variety of addition and cycioaddition reactions, for example with chalcogcns, aikynes, and azides.
