Veszpremi, Tamas,Barta, Istvan,Nagy, Jozsef

, p. 243 - 250 (2007/10/02)

The members of the series R(n)Si(NCO)(4-n) and R(n)Si(NCS)(4-n), where R = -CH3 and -C6H5, were prepared, their ultraviolet spectra recorded and the observed bands assigned.The spectra were compared to those of halogeno derivatives.The similarity of halogen- and pseudohalogeno-groups and difference between the effect of methyl- and phenyl-groups were studied.
