Conditions & References General procedure for the scope of silicon enolates (mechanical slow-injection method) General procedure: In a 30 mL round-bottomed flask was placed 20 mg of Sn-Mont. Sn-Mont was activated under vacuum at 120 oC for 1 h. Then, into the flask was added 0.9 mL of chlorobenzene and the suspended mixture was heated at 120 oC. Into the mixture was added a solution of 1.0 mmol of the alcohol 2a and 2.0 mmol of the silicon enolates in 1.1 mL of chlorobenzene dropwise with a syringe pump for 15 min. After the addition was completed, the mixture was further heated at 120 oC for 15 min. The mixture was then cooled to room temperature. The solid catalyst was filtered off, and the filtrate was concentrated and applied to NMR analysis. The desired alkylated product was isolated through the purification of the concentrated mixture by silica-gel column chromatography. With tin hydroxide-embedded montmorillonite in chlorobenzene, Time= 0.5h, T= 120 °C Tandiary, Michael Andreas; Asano, Masashi; Hattori, Taiki; Takehira, Satoshi; Masui, Yoichi; Onaka, Makoto; Tetrahedron Letters; vol. 58; nb. 20; (2017); p. 1925 - 1928 View in Reaxys OH
