本文报道了含氟不饱和酯的~(13)C化学位移和偶合常数。并根据碳上电荷转移、杂化程度以及邻接基团的电荷密度,解释了炔碳的化学位移和氟碳偶合常数。
In this paper, ~ (13) C chemical shifts and coupling constants of fluorinated unsaturated esters were reported. The chemical shifts and fluorocarbon coupling constants of alkyne carbon are explained based on the charge transfer on carbon, the degree of hybridization and the charge density of adjacent groups.
