Abstract
New bis-phosphines based on pamoic acid have been synthesised by the reaction of pamoic acid with PCl3. Alternatively new amides were synthesised from pamoic acid and n-butylamine. using N,N'-carbonyldiimidazole as an activation agent. The reaction of these amides with phosphorus trichloride in toluene leads easily to the highly sensitive chlorophosphines which react with trimethylsilylmorpholine to give the corresponding di-phosphines. The new compounds formed from the reactions have been characterised spectroscopically and in one case by X-ray crystallography. (C) 2001 Elsevier Science Ltd. All rights reserved.
