He wāhanga nui te hanganga matū o te rangahau pūtaiao hou me te whakaputa ahumahi. Kei roto i tēnei ko te whakaputa i ngā matū hou mā roto i ngā tauhohenga matū maha, ā, ko tētahi matū matua e whai wāhi nui ana ki tēnei tukanga ko te konutai cyanoborohydride.
Konutai cyanoborohydride, me te tātai matū NaBH3CN, he matū whakaiti kaha maha-mahi e whakamahia whānuitia ana i roto i te matū waro. He mea nui tēnei mō tōna kaha ki te whakaiti i ngā aldehyde me ngā ketone ki roto i ō rātou ake waipiro, ā, he mea nui tēnei i roto i te hanganga o ngā rongoā, ngā matū pai, me ētahi atu matū waro.
Ko tētahi o ngā painga matua o te whakamahi i te konutai cyanoborohydride hei kaiwhakaiti ko ōna āhuatanga tauhohenga ngāwari. He rerekē ki ētahi atu kaiwhakaiti e whakamahia whānuitia ana pērā i te konupūmā konupūmā konupūmā,konutai cyanoborohydrideKa mahi i raro i ngā āhuatanga ngawari ake, ā, he pai ake te haumaru me te watea ki te whakamahi i roto i ngā taiao taiwhanga. Mā tēnei ngawari ka taea te whakahaere pai ake i te tauhohenga, ka whakaiti i te tūponotanga o ngā tauhohenga taha kāore e hiahiatia, te whakaiti nui rānei i ngā matū ūnga.
Ko tētahi atu painga nui okonutai cyanoborohydrideko tōna tino whiriwhiringa. Ina whakamahia hei whakaiti i ngā pūhui carbonyl, ka karohia te pokanoa ki ētahi atu rōpū mahi kei roto i te ngota, ka hua ake he tauhohenga ma, he pai ake hoki. He mea nui tēnei whiriwhiringa i roto i te hanganga o ngā ngota waro matatini, he mea nui te tiaki i ētahi atu rōpū mahi mō te hanganga matū me ngā āhuatanga e hiahiatia ana.
Haunga te noho hei kaiwhakaiti,konutai cyanoborohydrideka taea te whakamahi i roto i ētahi atu whakarerekētanga matū. Ka taea te whakamahi mō te whakaiti i te hanga o ngā aldehydes me ngā ketones, tae atu ki te hanga o ngā momo matū heterocyclic. Nā tōna ngāwari ki te whakamahi me te hototahi ki ngā momo rōpū mahi maha, he taputapu whai hua tēnei mō ngā kaimātai matū e anga atu ana ki ngā momo wero hanga.
Hei tāpiritanga,konutai cyanoborohydridee mōhiotia ana mō tōna pumau me te ngāwari ki te whakahaere. He rerekē ki ētahi atu matū tauhohenga, ka taea te penapena me te kawe me te kore he tūpato nui, ā, he mea whai hua ake i roto i ngā taiao mātauranga me ngā taiao ahumahi.
Ahakoakonutai cyanoborohydrideHe maha ngā painga, he mea nui kia mōhiotia, pērā i ngā matū katoa, me āta whakahaere, me te whai i ngā tikanga haumaru e tika ana. Ahakoa e kiia ana he haumaru ake i ētahi atu matū whakaiti, he matū kaha tonu, ā, me mahi ngā mahi whakatūpato e tika ana i raro i te arataki a tētahi kaimātai matū mohio.
Hei whakamutunga,konutai cyanoborohydrideHe mahi nui tā te matū i roto i te hanganga matū, inā koa i roto i te whakaiti i ngā pūhui carbonyl me ētahi atu huringa e pā ana. Nā ōna āhuatanga tauhohenga ngawari, tōna whiriwhiringa teitei, tōna ngāwari, me tōna pumau, he taonga nui tēnei i roto i te pouaka taputapu a te kaimātai matū hanga. I te haere tonu o te rangahau me te whanaketanga i roto i te mara o te matū waro, ko te hiranga okonutai cyanoborohydridehei whakahohe i ngā huringa matū hou, me te hanganga o ngā pūhui hou, tera pea ka noho tonu te hiranga.
