摘要: The natural abundance carbon-13 chemical shifts of the nitrite ester (9; R = CH3)(diatretyne 2 methyl ester) and a series related acetylenic compounds have been measured correlated with structure. effect various substituents carbon–carbon triple bond on shift immediate carbon nuclei is discussed.
