Webn-Hexane can enter the environment from these landfills. n-Hexane also enters the environment from accidental spills during transport and leaks from storage containers. n-Hexane evaporates very easily into the air. Once in the air, n-hexane can react with oxygen and be broken down. n-Hexane released into the air is broken down in a few days.
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.
