“…4-Iodobenzophenone was prepared by a Friedel-Crafts acylation of iodobenzene by benzoyl chloride. 79 All chemicals were purified by distillation or recrystallization; 1 H-NMR and 13 C-NMR spectra were recorded to check the level of purity. The solvent N,Ndimethylformamide (DMF) was obtained from Aczo and the supporting electrolyte tetrabutylammonium tetrafluoroborate (Bu 4 NBF 4 ) was prepared using standard procedures.…”

“…Dehydration is therefore mainly used for the preparation of polyarylallenes in which at least three aryl groups are directly attached to the aliene bond (47,570,618). Thus, tetraphenylallene may be obtained in up to 53% yield by heating the corresponding alcohol [Ph2C (OH) CH=CPh2 ] with acetic anhydride (197,588,592) or potassium bisulfate (166), or simply by heat alone since the hydroxyl group is comparatively labile (616).…”
