Cyclizations in the homolytic reactions of unsaturated nitriles with tert-butylmercury halides in the presence of proton donors

Cyclizations are observed in the homolytic reactions of t-BuHgI with CH2=CHCH2YCH2CN [Y = CH2, O, CMe2, C(CO2Et)2, NCH2CN] and CH2=CHCH2CH2

α-ALKYLATION AND α-ALKYLIDENATION OF CARBONYL COMPOUNDS BY O-SILYLATED ENOLATE PHENYLTHIOALKYLATION

For many reactions next to a carbonyl group, the use of O-silylated enolate chemistry offers improvements in yield and selectivity over the corresponding reactions of Group I metal enolates.In the case of α-alkylation of carbonyl compounds, Lewis acid (TiCl4 or ZnBr2) promoted phenylthioalkylation of O-silylated enolates 3 by α-chlorosulphides 4 (R3=H, Me, Prn, Pri, Bui, and Me3Si), followed by reductive sulphur removal by Raney nickel, 5->6, is found to be a reliable method for this synthetically important C-C bond forming step.An alternative sulphur elimination pathway via the sulphoxide, 5->7, allows the regio- and stereocontrolled α-alkylidenation of carbonyl compounds.The phenylthioalkylation reaction is applicable to ketones, aldehydes, esters, and lactones.

α-Alkylation and α-alkylidenation of carbonyl compounds: Lewis acid-promoted phenylthioalkylation of o-silylated enolates

The O-silylated enolates of ketones, aldehydes, esters, and lactones can be phenylthioalkylated in the presence of Lewis acids; reductive or oxidative sulphur-removal gives the regiospecifically α-alkylated or alkylidenated carbonyl compounds.
