2-Iodothiophene (TP-I, Thiopheyl iodide, 2-ThioPhenyl iodide) is used as an intermediate in the synthesis of TP2P (ThioPhenyl-2-Propanone, 2-Thienylacetone). 2-Iodothiophene can react with ethyl acetoacetate and sodium ethoxide using CuI (Copper Iodide) and then reacted with hydrochloric acid and heated. 2-Iodothiophene can also undergo grignard reactions to obtain TP2Pol (ThioPhenyl-2-Propanonl, 2-Thienylisopropanol).
2-Iodothiophene has been obtained by addition of half of 50% aqueous nitric acid dropwise to a mixture of iodine and thiophene with vigorous stirring. As soon as the evolution of gases subsided the rest of the aqueous nitric acid was added to the reaction mixture and refluxed for 30 min. The organic layer was separated and steam distilled to obtain 2-iodothiophene.
Iodination of thiophene with iodine and mercuric oxide at 0°C gave a mixture of 2-iodothiophene (70%) and 2,5-diiodothiophene. 2-Iodothiophene has been exclusively obtained by nitrating thiophene with a mixture of iodine and nitric acid at 90°C. An easy approach for iodination of thiophene is the reaction of iodine with lithiated thiophene.

Tony: I iodinated thiophene using nitric acid and slowly added it, then refluxed it for 30 minutes at 90 °C. I obtained 2-Iodothiophene.

Get the 2-Iodothiophenemug. The equation of choice among math paradoxers and recreational mathematicians, who unspokenly derive much satisfaction in exposing students’ fallacious or illogical reasoning that leads to the contradictory result.
Be it due to division by zero or squaring (or square rooting) both sides of an equation, few students wouldn’t want to know why “1 = 2” is logically plausible.

Get the 1 = 2mug. Boy: I wanna ask her out
Girl: then do it!
Boy: what if they say no?
Girl: it’s February 2!
Boy: okay
Boy: I like you. Will you go on a date with me?

Get the February 2mug. When you and your lover order the 2 for $20 deal at Chili's, and fuck in the bathroom while you wait for the food to arrive. Return to the table, eat the meal, and fuck again while you wait for dessert.
License to grill!
License to grill!
Chili's is offering the 2 for $20 again, so Ashley and I got the steak, the lava cake, and double oral all for $20!
Whatta deal!
Whatta deal!

Get the 2 for $20mug. One of the devious marketing spawns from MTV headquarters (While claiming to show music videos 24/7) shows old episodes of "making the video" and other old shows that have been pushed out of MTV's rotation and excessive hip-hop. This premium cable channel has substantially longer commercials than other stations.

Get the MTV 2mug. Someone (usually a gay guy) who sucks a fart out of another's asshole and holds it in like a bong.
Also known as "Puffing A 2" or the act of passing on a fart to another person is known as "Passing A 2"

Get the A #2 Puffermug. Reference to Fight Club, whose two first rules were both 'Do not talk about Fight Club'. May be used for anything secret, particularly an organization or group of some sort.

Get the 1 and 2mug.
