Bischelate complexes of germanium with different chelate rings were prepared by double transmetallation. The earlier reported (O,O)-chelate [from the reaction of trichloro(chloromethyl)germane and N,N-dimethyl-2-(trimethylsilyloxy)-2-phenylacetamide (1)], 2-[dichloro(chloromethyl)germyloxy]-N,N-dimethyl-2-phenylacetamide (2) was reacted with trimethylsilylamides, 2,2-dimethyl-3-trimethylsilylbenzo[2H]-1,3-oxazin-4-one (5, B–SiMe3) and 4-methyl-1-trimethylsilylquinolin-2-one (6, Q–SiMe3) resulting in mixed (O,O),(C,O)bischelate complexes, 2-[dichloro[(2,2-dimethyl-4-oxo-2H-benzo[e][1,3]oxazin-3(4H)yl)methyl]germyloxy]-N,N-dimethyl-2-phenylacetamide (7) and 2-[dichloro[(4-methyl-2oxoquinolin-1(2H)-yl)methyl]germyloxy]-N,N-dimethyl-2-phenylacetamide (8). Crystallographic analyses established pentacoordination of germanium in 2 and hexacoordination in 7 and 8; the latter two compounds are the first reported mixed (O,O), (C,O)-bischelate complexes with two O→Ge coordinate bonds.
