Abstract The intramolecularly stabilized organogallium and organoindium compounds ClGa(CH 2 CH 2 CH 2 NMe 2 ) 2 ( 1 ), RIn(CH 2 CH 2 CH 2 NMe 2 ) 2 (R = Cl, Br, I, CN, SCN, CF 3 CC, MeCC, Me 3 SiCC, C 6 F 5 O, CF 3 CO 2 , CF 3 , i C 3 F 7 ,( 2a–13a ), RIn(CH 2 CH 2 CH 2 NEt 2 ) 2 (R = Cl, I, CN, CF 3 CC, MeCC, Me 3 SiCC, C 6 F 5 O, CF 3 CO 2 ( 2b , 4b , 5b , 7b–11b ) ClGa(C 6 H 4 CH 2 NMe 2 -2) 2 ( 14 ), ClIn(C 6 H 4 CH 2 NMe 2 -2) 2 ( 15 ), and ClIn[CH 2 CH 2 CH 2 N(CH 2 ) 5 ] 2 ( 16 ) a well as the homoleptic compounds GaR 3 (R = CH 2 CH 2 CH 2 NMe 2 ( 17 ), CH 2 CHMeCH 2 NMe 2 ( 18 ), C 6 H 4 CH 2 NMe 2 -2 ( 19 ) and In(CCCF 3 ) 3 (THF) 2 ( 20 ) have been synthesized from gallium trichloride or indium trichloride and the corresponding ω-aminoorganyl lithium compounds, by the reaction of 2a and 2b with the appropriate RLi, or from Cd(CH 2 CH 2 CH 2 NMe 2 ) 2 and RInBr 2 (R = CF 3 , i C 3 F 7 ). The 1 H-, 13 C-NMR and mass spectra of the new compounds as well as the X-ray crystal structure analyses of 1 , 4a , 14 , 17 , 19 and 20 are reported and discussed.
