Catalysis of Pd(II)-catalyzed acetalization of alkenes with diols
Hosokawa,Ataka,Murahashi

Alkenes bearing electron-withdrawing substituents are catalytically acetalized with 1,3-propanediol only by the use of PdCl2(MeCN)2 catalyst under O2 atmosphere. When a combination of BiCl3 and LiCl is used as co-catalyst, the acetalization proceeds effectively. These results indicate that a hydroperoxopalladium(II) species is most likely an active catalyst in the present reaction.
Photoinduced Molecular Transformations. Part 113. One-step Transformations of Cyclic Ethers into ω-Iodoalkyl Formates and of Aldehyde Cyclic Acetals into Monoesters of α,ω-Alkanediols by Iodoxyl Radical

The reaction of cyclic ethers with iodoxyl radical and iodine oxide gives the corresponding ω-iodoalkyl formates in one step; tetrahydrofuran can be transformed into ω-iodoalkyl formate in 31percent yield.Aldehyde cyclic acetals under conditions similar to the reaction of cyclic ethers lead to monoesters of α,ω-alkanediols in one step; cyclohexanecarboxaldehyde ethylene acetal gives 2-hydroxy cyclohexanecarboxylate in 60percent yield.The pathways leading to ω-iodoalkyl formatesand monoesters of α,ω-alkanediols are discussed based on the results of 18O-labelling studies with (18)OI and I2(18)O.
