Abstract
THE reaction between hydrobromoauric acid and magnesium pentamethylene bromide in ethereal solution proceeds somewhat differently than with the simpler magnesium alkyl bromides1. A colourless, crystalline, sparingly soluble salt is obtained which must be spirobis(pentamethylene)gold bromide (i). This compound has been identified through its ethylenediamine derivative, ethylenediaminospirobis-(pentamethylene)gold bromide (ii), which is a fairly stable colourless crystalline salt having a greater solubility in water than compound (i).
