Ka whakakapia te konganuku e te Boron: Ka hangaia e te huānga he matatini ki ngā olefin

Te whakakore i ngā konganuku taumaha paitini me te utu nui i roto i te umanga matū: E tohu ana tētahi pukapuka hou mai i Te Whare Wānanga o Würzburg Chemistry i te huarahi whakamua.

Kei te rangahau te tīma e arahina ana e te ahorangi matū a Holger Braunschweig i Te Whare Wānanga o Würzburg i ngā āhuatanga 'whakaari-whakarewa' o ngā huānga rōpū matua pērā i te boron. Kua whakaatuhia e rātou i raro i ētahi āhuatanga, ka taea e te boron te whai i te whanonga tauhohenga o ngā konganuku me te kore e paitini, e utu nui rānei pērā i ngā konganuku.
Koinei te pūtake o tētahi whakaputanga hou nā te rōpū Braunschweig i roto i te puka Nature Chemistry. E whakaatu ana te tuhinga ka taea hoki e te boron te hanga i ngā mea e kiia nei he matatini π me ngā olefin, he rite tonu ō rātou āhuatanga me ō rātou whanonga ki ngā matatini o ngā konganuku whakawhiti me ngā olefin. Ko ēnei matū whakamutunga he takawaenga i roto i te maha o ngā tukanga whakatere nui i roto i te ahumahi.
He Whakaaweawe mō Ētahi Atu Kairangahau
"Nā tā mātou kitenga i huaki tētahi wāhanga hou o te ripanga ā-pūmotu mō te matū taunga π – tae atu ki te āheinga ki te whakamahi i ngā huānga rōpū matua hei whakakorikori ahumahi mō ngā tauhohenga mahi o ngā hauwaiwai kore-māku," te kī a Holger Braunschweig.
Nā ngā tohunga rangahau tuarua, a Tākuta Maximilian Michel rāua ko Tākuta Marco Weber i hanga ngā matatini π boron-olefin. Ko te tumanako a ngā tohunga matū o Würzburg mā tā rātou kitenga ka whakahihiko i ētahi atu kairangahau ki te pana atu i ngā rohe o te matū rōpū matua, me te kimi i ētahi atu tono mō te boron, mō ētahi atu huānga rōpū matua rānei.
Te Whakakapinga i ngā Konganuku Taumaha ki ngā Huānga Rōpū Matua
"Mō te wā roa, ko tā mātou whāinga matua he whakakapi i ngā konganuku taumaha paitini me te utu nui i roto i ngā tukanga ahumahi ki ngā huānga rōpū matua," te kī a Holger Braunschweig.
Muri iho, e hiahia ana te tīma ki te whakarerekē i ngā matatini boron-olefin π kia rite ake ai tō rātou whanonga ki ērā o ngā matatini konganuku e mōhiotia ana.
Ngā Hoa me ngā Kaitautoko
I whakaputa tahi te tīma o Würzburg i ēnei hua me ngā rōpū i arahina e Ahorangi Arumugam Jayaraman o Te Whare Wānanga o Nevada i Las Vegas (USA) me Ahorangi Alfredo Vargas o Te Whare Wānanga o Sussex i Brighton (UK).
I tautokona te mahi e te German Research Foundation, te Alexander von Humboldt Foundation me te Natural Science and Engineering Research Council o Kanata.
