Dibalh hexanes storage
WebDec 1, 2010 · Reaction was run with 10 equiv of DIBALH (1 M hexane solution) in CH 2 Cl 2 (0.07 M). Next, we investigated the selective deprotection of 1,3-bis-silyl ethers, which were synthesized from a known diol 79, 10 ( Table 2 ). Treatment of bis-TBS ether 8a with 5 equiv of DIBALH afforded 78% yield of the primary alcohol 9a. WebExample 1. The SM (70 g, 300 mmol) was dissolved in hexanes (600 mL) and cooled to -78 C. A separate flask was charged with DIBAL-H (1.0 M in hexanes, 310 mmol) and also cooled to -78 C.The DIBAL-H solution was transferred via cannula over 20-25 min then stirred at -78 C for 1 h. The reaction mixture was quenched by adding MeOH (30 mL) …
