Massenspektren geradkettiger aliphatischer Ketone

Abstract: Der Zerfall geradkettiger aliphatischer Ketone im Massenspektrometer wurde bereits von Sharkey, Shultz und Friedell) studiert. Aus den Spektren gesattigter aliphatischer Ketone 1 wurde abgeleitet, daR aliphatische Ketone vorzugsweise in zwei Hauptspaltungsreaktionen abgebaut werden : 1) Es entstehen durch Abspaltung der Reste R1 oder R2 die Schliisselbruchstiicke 2 und 3, wobei angenommen wurde, da13 die Abspaltung eines schwereren Alkyl-Restes gegeniiber derjenigen eines leichteren begiinstigt ist 2).

“…The mass spectra of straight-chain aliphatic ketones (289), of acyclic a,ß-unsaturated aldehydes, ketones, and esters (290), of cyclic ß-diketones (291), of ,ß-epoxyketones (292), and of diazoketones (298) have been reported. On the mechanistic side, the loss of H20 from molecular ions of aliphatic ketones (294) and the effect of fluorine substitution on the McLafferty rearrangement of aliphatic ketones (295) have been studied.…”

“…The mass spectra of cyclohexanediols (382,333), ,ß-unsaturated secondary alcohols (334), a-and ß-decalols (335), synthetic and natural dimethylcarbinols (336), aliphatic 1,2-glycols (337), and branched long-chain aliphatic alcohols (338) have been discussed. The stepwise fragmentations of secondary and tertiary alcohols of higher molecular weight have been carefully studied (339). Reports on the mass spectra of alkylated bisphenols (340) and of benzofurans (341) have been published.…”
