FREE RADICAL CHAIN REACTION OF ALLYLIC TIN COMPOUNDS WITH ORGANIC HALIDES INVOLVING SH prime PROCESS.
Migita,Nagai,Kosugi
, p. 2480 - 2484 (1983)
Negatively substituted halomethanes were allylated easily by allyltin compounds via radical chain reaction involving S//H prime process. Aryl, aralkyl, and alkyl halides underwent similar chain reactions only when the tin compound was charged in excessive amounts.
Kinetic resolution of racemic secondary alcohols via oxidation with Yarrowia lipolytica strains
Fantin, Giancarlo,Fogagnolo, Marco,Medici, Alessandro,Pedrini, Paola,Fontana, Silvia
, p. 2367 - 2373 (2000)
Cyclic and alicyclic racemic secondary alcohols are kinetically resolved via oxidation with Yarrowia lipolytica strains. The comparison of the oxidation reactions with the reductions of the corresponding ketones supports the hypothesis of the presence of

Polyethylene-Bound Soluble Recoverable Palladium(0) Catalysts
Bergbreiter, David E.,Weatherford, David A.
, p. 2726 - 2730 (1989)
The use of diphenylphosphine-terminated ethylene oligomers as ligands for palladium(0) and palladium(II) is described.With use of these polymeric ligands, it is possible to carry out homogeneous reactions characteristic of (Ph3P)4Pd and (Ph3P)2Pd(OAc)2 with essentially complete recovery of the Pd catalyst.The only limitation to repeated reuse of the catalyst is its immolative catalytic oxidation of the phosphine ligand by adventitious oxygen.
PALLADIUM-CATALYZED REARRANGEMENT OF ALLYLIC ESTERS OF ACETOACETIC ACID TO GIVE γ,δ-UNSATURATED METHYL KETONES
Shimizu, Isao,Yamada, Toshiro,Tsuji, Jiro
, p. 3199 - 3202 (1980)
Various allylic esters of acetoacetic acid undergo rearrangement to give γ,δ-unsaturated methyl ketones in high yields with elimination of carbon dioxide under mild conditions in the presence of catalytic amounts of Pd(OAc)2 and PPh3.

An efficient method for deprotection of acetals
Saravanan,Chandrasekhar,Anand, R. Vijaya,Singh, Vinod K.
, p. 3091 - 3092 (1998)
A variety of acetonides and acetals were efficiently cleaved using CuCl2.2H2O in MeCN. The method was effectively used in synthesis of chiral diols which are important in asymmetric synthesis.
Chromium-Catalyzed Production of Diols From Olefins

Paragraph 0111, (2021/03/19)
Processes for converting an olefin reactant into a diol compound are disclosed, and these processes include the steps of contacting the olefin reactant and a supported chromium catalyst comprising chromium in a hexavalent oxidation state to reduce at least a portion of the supported chromium catalyst to form a reduced chromium catalyst, and hydrolyzing the reduced chromium catalyst to form a reaction product comprising the diol compound. While being contacted, the olefin reactant and the supported chromium catalyst can be irradiated with a light beam at a wavelength in the UV-visible spectrum. Optionally, these processes can further comprise a step of calcining at least a portion of the reduced chromium catalyst to regenerate the supported chromium catalyst.
Oximinotrifluoromethylation of unactivated alkenes under ambient conditions

An efficient protocol for oximinotrifluoromethylation of unactivated alkenes was developed via trifluoromethyl radical-induced intramolecular remote oximino migration under mild reaction conditions, providing a wide range of β-trifluoromethylated oximes. Other fluoroalkyl radicals were also applicable for this transformation. This method provided access to synthetically challenging medium-sized ring scaffolds and the 6,7,5-fused lactam skeleton.
