Notizen:
The title [4]radialene 1 reacts with N1-methyltriazolinedione or with the iodine(III) salt PhI+ O+IPh · 2 BF4- in CH2Cl2 by oxidative elimination of only one dimethylsilyl unit to form the functionalized 3,4-bis(alkylidene)1-1-cyclobutene 2 or its hydrolysis products, (Z)-4 and (E)-4. When the iodonium salt is used in CCl4, rearrangement of the radialene framework occurs, and the bicyclic fluorodimethylsilyl enol ether 9 is obtained. An X-ray crystal structure analysis of 9 indicates a weak coordination between a carbonyl oxygen atom and a silyl group.
