✦ Synopsis

Reaction of equimolar amounts of the ferriophosphaalkene P; M = Al (2a), Ga (3a), In (4a) and E = As; M = Al (2b), Ga (3b), and In (4b). These compounds feature η 1 -coordination [(η 5 -C 5 Me 5 )(CO) 2 FeP=C(NMe 2 ) 2 ] (1a) or the ferrioarsaalkene [(η 5 -C 5 Me 5 )(CO) 2 FeAs=C(NMe 2 ) 2 ] (1b) with trimethyl-of the phosphaalkene or the arsaalkene ligand towards the Lewis acid via the pnictogen atom. The molecular structures aluminium, trimethylgallium and trimethylindium afforded the adducts [(η 5 -C 5 Me 5 )(CO) 2 FeE{MMe 3 }C(NMe 2 ) 2 ] with E = of 2a and 3a were elucidated by X-ray diffraction analyses.
