N. Tokitoh et al., THERMAL RETROCYCLOADDITION OF OVERCROWDED GERMIRENES - A NEW METHOD FOR THE GENERATION OF GERMYLENES, Chemistry Letters, (9), 1995, pp. 827-828
Thermolysis of overcrowded 2,3-diphenylgermirenes bearing bulky substi
tuents on the germanium atom in benzene affords the corresponding kine
tically stabilized germylenes, the efficient formation of which is evi
denced by the trapping experiments with 2,3-dimethyl-1,3-butadiene. Th
is provides a new and mild method for the generation of germylenes.
