  Abstract:  Potential precursors of phosphagermaallenes based on the use of dimethyl-benzyl-amine as a substituent on the group 14 element were designed. The proper orientation of the lone pair on the nitrogen towards the germanium atom could enhance the electron density around the germanium, thus stabilizing the –P=C=Ge< unit. Three novel phosphagermapropenes have been obtained and evidenced through NMR spectroscopy. The solid state structure of a novel organometallic germanium derivatives is also discussed.

Keywords: phosphagermapropenes, heteroallenes, 2-substituted (N,N-dimethyl-aminobenzyl ligands, organogermanium derivatives
