✦ Synopsis
Duriw the cour.;e of' our utudie:.: on quinonoid comDunds, it has been found that tetrachloro-ebee:izoquino.r\e (I) has pronounced c.yzostatic activity. *This stimulated us to investigate its reactivity toward the known cytostatic agent, l,l-dicyano-2-(2-furyl) ethylene (IIa)'. It is found that (I) adds preferentially to the double bond of the fury1 residue to give the l,4-dioxen (IIla) leaving the 2-vinyl side chain intact. It adds similarly to the analogous 2-vinylfurans (iIb-e) in boiling benzene to give the corresponding 1,4-dioxcn derivatives, (IIIb-e). Thus, in this respect the isolated furan 11

## Abstract The reactions of (__E__)‐bis(2,4,6‐tri‐tert‐butylphenyl)diphosphene with tetrachloro‐o‐benzoquinone gave two products of interest, a spirophosphorane and a 1,3,2‐dioxaphospholane, indicating cleavage of the P=P bond. The structures were determined by X‐ray crystallographic analyses. © 2
