✦ Synopsis

In the recent communication 2) we have described the generation and the reaction of phenalenylidene (2, a novel carbene species In which the divalent carbon center was incorporated with a phenalenyl conjugated system , and the triplet electronic ground state (3, has been suggested aa an Intermediate in the thermal and the photochemical decomposition of sodium salt (3) of phenalenone tosplhyd raeone. The present paper deals with the reaction between phenaleuylfdene (2) and cycloheptatriene and provides evidence for the first example of 1,6-addition of carbene species onto cyclic polyene. 3)
