Dibzu

Trumps Dibs. Beats shotgun. Beats all other means of calling.

Example 1:
Guy 1: "Damn bro look at that ass"
Guy 2: "Dibzu!"

Guy 2 now owns full right to try and talk to said girl before his friend is allowed.
Example 2:
Guy 1: "Everybody get in the truck."
Guy 2: "Shot gun!"
Guy 3: "Dibzu!"
Guy 2: "Damn."

Dibutyl ether

Dibutyl ether is an ether that is used for complex grignard reactions where higher temperatures are needed. Dibutyl ether is good for reacting benzyl magnesium chloride (made from benzyl chloride and magnesium turnings in dibutyl ether) with acetonitrile in dibutyl ether at elevated temperatures. Then reacting it with hydrochloric acid to get Phenyl-2-Propanone. Dibutyl ether increases the yield compared to diethyl ether. Dibutyl ether is produced by reacting butanol with sulfuric acid. The temperature cannot be too high, as butanol could dehydrate into butene (1-butene). The ether must be stored with butylated hydroxytoluene as explosive peroxides can form.
