合成了Ar分别为C_6H_5-,m-CH_3C_6H_4-,O-CH_3OC_6H_4-,p-CHOC_6H_4-和P-Cl-C_6H_4-的ArOCH_2CH(OH)CH_2NHR(R=3-吡啶甲酰基)五个新化合物。在反应过程中,对中间体进行鉴定时,发现肼解产物为相应的ArOCH_2CH(0H)CH_2NH_2和邻苯二甲酰肼的混合物,而不是象Hermann J. Roth所报道的单一化合物Ⅶ。
The similarities of The mass spectra of any two isomers (n and m) are represented by a similarity index [SI(n, m)]. The similarity index is calculated using a novel formula: SI(n, m) ={min[R(n, i), R(m, i)] / max[R(n, j), R(m, i)]} 100 Where R(n, j) and R(m, j) are The intensity ratio of a fragment pair (j); j is an ordinal number which is arbitrarily assigned to a selected pair of fragments. The value of similarity index ranges from 0 to 100, when n = m, The SI(n, m) = 100. Similarity indices of mass spectra of isomeric tetradecadien-1-ols were calculated by The "min.-max." Fuzzy similarity analysis. The universality of The method was confirmed by The testing with mass spectra of ten isomers of tetradecadien-1-ols.
