of vanillin with phosphoryldichlorides. The di(4-hydroxymethyl-2-ethoxyphenyl)phosphates (DHMPP) were prepared by the reduction of DFMPP with potassium borohydride. The 31P-1H coupling in DFMPP (compounds 1a-h) was investigated and the splitting of the 31P signal by the 1H nuclei was observed only with the alkyl DFMPP (1a-e). In the non-decoupled 31P spectra a quartet at −11.3 ppm was seen for la (P-OCH
摘要 通过香草醛与磷酰二氯缩合合成磷酸二(4-甲酰基-2-甲氧基苯基)酯(DFMPP)。二(4-羟甲基-2-乙氧基苯基)磷酸酯(DHMPP)是通过用硼氢化钾还原 DFMPP 制备的。研究了 DFMPP(化合物 1a-h)中的 31P-1H 偶联,仅用烷基 DFMPP(1a-e)观察到 1H 核对 31P 信号的分裂。在非去耦 31P 光谱中,la (P-OCH 3) 的四重峰 JPH=11.4 Hz,以及 1b、1c、1d 和 1e 的三重峰(1b,P-OCH 2 δ= - 12.3 ppm, JPH=8.4 Hz; 1c, P-OCH 2CH2CH3, δ= - 12.6 ppm, JPH=7.1 Hz; 1d, P-OCH 2CH2CH2CH3, δ= - 12.9 ppm, JPH=8.4 Hz 和le, P-OCH 2CH2Cl,δ= - 13.0 ppm,JPH = 8.1 Hz)。
