Treatment of 3,8-diacetyldeuteroporphyrin IX dimethylester 6 with phosphoryl chloride and N,N-dimethylformamide gives the 3,8-bis(1-chloro-2-formylvinyl) derivative 7 which affords the corresponding 3,8-diethynyl derivative 2 upon treatment with base; compound 2 and its iron(III) chloride dimethylester are fully characterized.
