Methyl N-(4-Chlorophenylaminothiocarbonyl)benzimidate

Synthesis, Spectral and Structural Study of N-[1-(N,N,N?,N?-Tetramethylphosphoramidoyl)- 1H-Benzimidazol-2-yl]-Propionimidic Ethyl Ether

“…The P N4 (1.6304(10)Å) and P N5 (1.6245(9)Å) bond lengths are shorter than P N1 (1.7248(9)Å) and are thus shorter than a standard single P N bond (1.73Å) [19]. The C N bond length (1.2777(13)Å) of the imidic group is the same as in pure unconjugated C N (1.27Å) [20] and approximately the same as for C N imidate bond (1.265Å) [14,15,21]. This may be explained by the absence of conjugation between the n and π electrons inside the imidate function (O C N).…”
