I-Dess-Martin Periodinane (DMP) (i-CAS: 87413-09-0), i-reagent ye-iodine ephezulu, isetyenziswa ngokuqhelekileyo, ithambile, kwaye i-reagent ekhethiweyo ye-oxidation.Iingenelo zayo ziimeko zokusabela kancinci, isantya esiphakathi, idosi encinci kunye nonyango olulula lwasemva.
I-Dess-Martin Periodinane i-reagent eluncedo kakhulu esetyenziselwa i-oxidation ye-alcohol ephambili kwi-aldehydes kunye ne-alcohol yesibini kwii-ketones.I-Dess-Martin Periodinane iphinda isetyenziswe njenge-oxidant ye-complexes ene-alcohol esebenzayo.Ibandakanyeka ngokusebenzayo kwi-oxidation ye-N-ekhuselweyo-amino alcohols ngaphandle kwe-epimerization kunye ne-alcohol alcohols.
I-Dess-Martin Periodinane yi-reagent epholileyo, eguquguqukayo yokukhethwa kwe-oxidation ye-alcohol ephambili kunye neyesibini kwi-aldehydes kunye ne-ketones, i-hydroxamic acids kwi-acyl notroso compounds, ukukhuselwa kwe-thioacetals, i-deoximation ye-ketoximes kwii-ketones.
Kwiminyaka yakutshanje, iikhompawundi eziphezulu ze-iodine njengohlobo lokulungiselela lula, ukusebenza kancinci, ii-reagents ezintsha ze-organic synthesis, ezikhetha kakhulu kwaye zinobuhlobo nokusingqongileyo, zisetyenziswa ngokubanzi kwi-organic synthesis yanamhlanje.I-Dess-Martin Periodinane yenye yezona zinto zifundwa kakhulu kwaye zisetyenziswa kakhulu kwi-reagents.
I-2-Iodobenzoic Acid (50.0g, 0.20mol) yongezwa kwi-sulfolane (250mL), isisombululo satshiswa kwi-50 ℃.I-90% yesicombululo singentla sathi chu sidityaniswa ngokucothayo kwisisombululo esinamanzi (147.4 ml) se-potassium hydrogen persulfate (0.24g, 1.2 mol, eq) ku-50℃, kwaye impendulo yafukanyelwa iiyure ezi-3.Emva koko, isisombululo sokusabela safudumeza ukuya kuma-95 ℃.Kwaye i-10% eseleyo yesisombululo se-2-iodobenzoic acid yongezwa ngokucothayo kwisisombululo sokusabela, kwaye impendulo yaqhubeka iiyure ezi-3.Emva kokugqitywa kwempendulo, yapholiswa ukuya kwi-5 ℃ kwaye ukuvuselela kwaqhubeka kulo bushushu kwiiyure ze-1.5.I-1L yamanzi yongezwa ngokushukumisa kwaye yahluzwa (ifiltrate yayiza kuphinda isetyenziswe).Ikhekhe lokucoca lihlanjululwe ngamanzi kunye ne-acetone ngokulandelelana kwaye yomiswa kwiqondo lokushisa kweeyure ze-16 ukufumana i-53.2g ye-2-iodoylbenzoic acid (isivuno: 95.04%), emhlophe eqinile kunye ne-99.7% yococeko (eqinisekiswe yi-NMR kunye ne-HPLC).Ifunyenwe yi-HNMR, I-solid yayizimisele ukuba yi-2-iodoylbenzoic acid.I-2-iodoylbenzoic acid (i-45g, i-0.16mol) yongezwa kwi-acetic anhydride (49G, 0.48mol) kunye ne-dioxane (90ml), ilandelwa yi-B (C6F5) 3 (0.0016mol), isisombululo sokuphendula satshiswa kwi-50 ℃.Kwaye ixutywe imizuzu eyi-10, kwaye emva koko i-solvent yachithwa phantsi koxinzelelo oluncitshisiweyo.Isisombululo reaction songezwa nge-methyl tert-butyl ether (400mL), ukufunxa yahluzwa, kwaye yomiswa kwiqondo lobushushu obuphakathi ukufumana okuqinileyo okumhlophe (61.1g, isivuno: 90%).Ukusulungeka kwaba ngama-99.1% (kungqinwe yi-NMR).
