    • (a) In related amino aryl diselenides, Wirth et al. have unequivocally established that an ethyl selenide (45% yield) is obtained upon treatment with diethylzinc. This ethyl selenide was proven not to be the dominant catalytically active species in the addition of diethylzinc to benzaldehyde (17% yield). Furthermore, these workers also provided NMR evidence for zinc selenolate dimers. See: Wirth, T.; Kulicke, K. J.; Fragale, G. Helv. Chim. Acta 1996, 79, 1957.
