Two Elimination Reaction Patterns Observation #2: One Elimination Is Sensitive To Stereochemistry And The Other Is Not Here's a quirky example of an elimination reaction If you treat this substituted cyclohexane with the strong base NaOEt you might expect to get the more substituted (tetrasubstituted) alkene with double bond between C 1 and C 2 But that's not what we actually get! In

The reaction is 2 NaOH(aq) + 2 Al(s) + 6 H2O(ℓ) −→ 2 NaAl(OH)4(aq) + 3 H2(g) What asked by Anonymous on May 1 2015 Chem Find specific heat capacity A piece of lead with a mass of 27 3 g was heated to 98 90oC and then dropped into 15 0 g of water at 22 50oC The final temperature was 26 32oC Calculate the specific heat capacity of lead from these data THANK YOU FOR ANY HELP!

Author: Subject: Reaction of sodium with DMF

Reaction of sodium with DMF In order to test out if dimethylformamide would be suitable as a liquid in which NaOH is soluble or reacts and which doesn't react with sodium (for use as a protective liquid in making Na/K alloy mineral oil is not suitable because the metal tends to form small drops which won't unite again) I added a peasized piece of sodium to a test tube containing about 5ml of DMF

The reaction is suggested to involve B(AC)2 ester cleavage facilitated by adventitious NaH-derived NaOH rather than the proposed E2 elimination of isobutylene by DMF-derived NaNMe2 Powdered KOH in THF is a significantly safer and simpler alternative that effects cleavage of tert-butyl benozoates at ambient temperature in excellent yield (94-99{%})

This reaction involving conjugated acetylenes and substituted benzylamines proceeded smoothly giving rise to tri-aryl substituted pyridines which are biologically relevant compounds in good to excellent yields in N N-dimethylformamide (DMF) under air at 140 C with K2CO3 as catalyst

The reaction is reversible and therefore will proceed to go the left if not driven towards the right If too little bleach was added some of the product could have been converted back to cyclohexanol This means that our purity was not perfect Conclusion The synthesis of cyclohexanone is a simple procedure that uses Acetic acid sodium hypochlorite hypochlorous acid ether sodium chloride

The toxic bicyclic octapeptide α‐amanitin is mostly found in different species of the mushroom genus Amanita with the death cap (Amanita phalloides ) as one of the most prominent members Due to its high selective inhibition of RNA polymerase II which is directly linked to its high toxicity particularly to hepatocytes α‐amanitin received an increased attention as a toxin‐component
