question:
In the Corey-Bakshi-Shibata catalyst, an atom of it is attached to a pyrrole ring, an oxygen atom, and a toluene group. This element's acids are combined with amines and ketones in the Petasis reaction and in combining alkyl halides through the Suzuki coupling. Complexes containing it are called sido or arachno according to Wade's rules, and a more famous reaction using it is sometimes named for Herbert Brown. Mined from the ore Uletite, its silicate was once used in making hard glass for manufacturing laboratory equipment. For 10 points, name this element that participates in an anti-markonikov addition reaction to alkenes, with atomic number 5 and symbol B.
answer:
Science


question:
The elimination mechanism by which the dehydration of its major product occurs necessarily involves the abstraction of an acidic hydrogen and displacement of the leaving group. The catalyst in this reaction itself is regenerated from the deprotonation of water in its final step, which results in the conversion of its intermediate, an alkoxide. An aldehyde or ketone had originally undergone a nucleophilic-addition-type process to produce that alkoxide, which had converted it from a nucleophilic enolate using a hydroxide ion catalyst. Producing a final product known as a beta-hydroxyaldehyde, FTP, name this condensation reaction whose name combines that of its two final products.
answer:
Science


question:
A leader from the latter phase of this conflict was Jacobus Hercules De la Rey, who would eventually be shot dead by police. One side in this war achieved victory at Spion Kop by compelling the other side to try raising the siege of Ladysmith. Frederick Sleigh Roberts was eventually successful in relieving Maefiking and Kimberly, and Horatio Kitchener introduced the "scorched earth" policy and the concentration camp in this war, whose belligerents included a republic led by Paul Kruger. FTP, name this 1899 to 1902 war ended by the Peace of Vereeniging, which was fought between Great Britain and the Afrikaner states of South Africa.
