Matt will one day those silyl environmentalists though cap and trade was a good idea too!
According to Hou, the unprecedented selectivity achievable through this method is due to a balanced interaction between the oxygen atom of the silyl ether adduct and the scandium cation.
Further experiments revealed that the combination of a silyl ether tether group and a scandium-based catalyst enabled controllable carbometalation on numerous unsaturated organic molecules-in many cases, with higher regioselectivity than any other catalyst.
However, when the researchers tethered a silyl ether-a group containing silicon, oxygen, and hydrocarbon atoms-to the end of the triple-bonded carbon substrate, the carbometalation proceeded with extremely high regioselectivity; over 99% of the final product was isolated as a single chemical isomer.
It's silyl and predicable but - 'Cletus n' Jetro don't want "the gummint taking are guns away."
