The Correlation of Tolman's Cone Angles with 1J(31p—1H) of Phosphonium FluorosulfonatesA 1H-n.m.r. study of three series of phosphonium salts [HPR3-nHn]X, and [HPPh2R1-nHn]X and (R = aliphatic substituent and H, X = SO3 F) gives a good relationship between increasing values of 1J(31P—1H) versus decreasing size of substituted phosphines. A method to obtain Tolman's cone angle is described.
Notes:
Die 1H-NMR-Untersuchung dreier Reihen von Phosphoniumsalzen [HPR3-nHn]X, [HPPhR2-nHn]X und [HPPh2R1-nHn]X (R = aliphat. Rest und H, X = SO3F) ergab einen inversen Zusammenhang von Werten der 1J(31p—1H)-Kopplungskonstante und Raumbedarf der Phosphine. Es wird eine Methode zur Bestimmung Tolmanscher Kegelwinkel auf der Basis von 1J(31p—1H)-Werten angegeben.
