I cannot quite follow your argumentation , since it is a simple acidbase reaction and there are no carbocations involved . There is a simple reason nBuLi is commercially available and quite cheap , whereas propynyllithium is a specialty reagent . <| sep |> Hmm I can see why that would be an issue but the public school I went to had several people indicted for embezzlement so I suppose those restrictions aren ' t in place for charters ? <| sep |> It ' s pretty common for pilots to be an episode that ' s not the beginning of the show , because it shows the audience and probably more importantly , the people with the money what a regular episode feels like . Look at Adventure Time , Steven Universe , and Over the Garden Wall the pilot being Tome of the Unknown , they were all like that . I honestly can ' t remember much of AT ' s early days , but if you compare the actual episode 1 of OTGW and Steven Universe , you ' ll see those are the actual beginnings of the story Wirt realizing they are lost , Steven summoning his shield while the pilots take place in the middle of the journey . Anyway , that ' s why nothing is explained . If there ' s ever a series , episode one will probably explain those things . Unless some of them are meant to be revealed progressively , like how the first episode of OTGW is very much a first episode but the beginning of the story is revealed later .
