Taupānga

1. Te takawaenga matū Te wai marama kore Tae Ka whakamahia hei takawaenga, ka whakamahia nuitia i roto i te ahumahi rongoora, te pūmua, te glycosides, te huaora, me etahi atu, Friedel-Crafts benzylation me te cyclohexylation reaction catalyst.
2. Ka whakamahia te ahumahi kirihou ki te whakakoi i nga tauhohenga whakahiato matū hei whakakorikori oligomerization me te whakarereke rapa silicone.
3. Ahumahi hiko mo te hanga i nga polymers hiko hiko
4. Ahumahi hinu hei whakakorikori mo nga tauhohenga protonation.
5. Nga patu patupatu waihanga me nga kaiwhakarite tipu i roto i te umanga ahuwhenua.
6. Mo te ahumahi huka.
7. Te rangahau taiwhanga mo nga tono tauhohenga motuhake Trifluoromethanesulfonic anhydride e whakamahia nuitia ana i roto i te whakahiatotanga o te alkyl me te vinyl trifluoromethanesulfonates. I roto i te whakahiato matū me te rongoa, ka whakamahia te catalysis ki te trifluoro anhydride, waikawa me te hākawa.
