(DIMETHYLAMINOETHYL)CYCLOPENTADIENYL LIGANDS IN THE CHEMISTRY OF GROUP-13 ELEMENTS (AL, GA, IN)

The synthesis of cyclopentadienyl complexes containing polydentate C(5)R(4)(CH(2)CH(2)NMe(2)) ligands (R = H, Me) and Group 13 elements (Al, Ga, In) is described. The compounds (C(5)Me(4)CH(2)CH(2)NMe(2)) AIX(2) (X = Me, Cl, Br, I), (C(5)Me(4)CH(2)CH(2)NMe(2))MCl(2), (M = Ga, In), (C(5)H(4)CH(2)CH(2)NMe(2))AIX(2) (X = H, Me, Et, Cl), (C5H4CH2- CH(2)NMe(2))GaCl2, and (C(5)H(4)CH(2)CH(2)NMe(2))InMe(2) are obtained by three different procedures. All compounds that have been characterized, so far, by X-ray diffraction studies show an additional intramolecular coordination of the nitrogen atom in the side chain. Monomeric structures and sufficient volatilities make them potential candidates for MOCVD processes.
