added the reaction was cooled in dry ice and after one hour a white precipitate was isolated by filtration this material was crystallized from 95 ethanol to yield 55 g 86 of white needles which had a melting point of 186 u00b0 c the nmr and ir spectra along with the elemental analysis were consistent with the title structure a clean reaction bottle was charged in a dry box with 7 3 g 0 02 mol of the iodonadimide prepared as described above 2 00 g 0 01 mol of oxydianiline 47 g of n n dimethylacetamide 0 314 g of triphenylphosphine 6 mol based on the iodonadimide 0 421 g bis triphenylphosphine palladium ii chloride 3 mol based on the iodonadimide and 3 65 g of 1 8 diazabicyclo 5 4 0 undec 7 ene 120 mol the reaction vessel was purged with carbon monoxide and then brought to a pressure of about 8 kg cm 2 in an oil bath after one hour a gas chromatograph analysis of the reaction mixture indicated that all of the oxydianiline had been consumed the remaining carbon monoxide pressure was released the reaction mixture was poured into ethyl alcohol and the solids collected by filtration a crude product of 7 0 g 100 was obtained proton nmr in dimethylsulfoxide showed resonances consistent with the following.
