✦ Synopsis
Thermolyses of cage lactones (2) and their corresponding lactols _ (7-J cause a formal dyotropic rearrangement. These novel reactions in cage system are discussed.

Oxidative rearrangement of dihydronaphthofuran 5 with aqueous ceric ammonium nitrate afforded the cage compound 7 which decomposed to diol 8 upon standing at room temperature. An X-ray structure obtained for diol 8 confirmed the formation of this novel cage structure.
The room-temperature reactions of Sn(NMe(2))(2) with less sterically demanding primary phosphines (RPH(2)) give the homoleptic phosphanediide compounds [SnPR](n) in high yields (R=tBu (1a), cyclohexyl (1b), 1-adamantyl (1c)). However, the room-temperature reaction of Mes\*PH(2) (Mes\*=2,4,6-tBu(3)C(
