[2,2,3,3-2H4]-3-Amino-1-propanol ([2,2,3,3-2H4]-6). As reported, 3-hydroxypropionitrile was reacted with NaOD/D2O(≥98 atom %D) to give [2,2-2H2]-3-deuterioxypropionitrile (DOCH2CD2CN) in 65% yield [Rf 0.52, EtOAc-hexanes (3:1)]. This nitrile was then reduced with LiAlD4 (98 atom %D) according to the literature to give the fina product [96% yield]. 1’,1’,2,2,3,3-[2H6]-3-(2’-Benzyloxyethylamino)-1-propanol([1’,1’,2,2,3,3-2H6]-8). With minor modification to a literature preparation of unlabeled material, AlD3 [from LiAlD4 (98 atom %D, 1.0 g 22.6 mmol)] was reacted with [2,2,3,3-2H4]-7 (1.5 g 6.4 mmol) for ~12 h. The flask was then cooled (ice bath), and the reaction was quenched with the dropwise addition of 1M sodium potassium tartrate (5.0 mL). The mixture was diluted with water (100 mL) and CH2Cl2 (50 mL); 40% NaOH (~1.0–1.5 mL) was added to insure a basic pH. The phases were separated, and the aqueous layer was extracted with CH2Cl2 (3 × 50 mL). All organic layers were combined dried (Na2SO4), filtered, and evaporated to afford the product (86%) as a pure, colorless oil [Rf 0.50 in NH3-saturated CH3OH : CH2Cl2 (1:9)].

Acetonitrile (MeCN) and ether were dried according to the literature procedures and distilled under Ar prior to use. Iodosylbenzene (PhIO) was prepared by a literature method. Non-heme iron(II) complexes, Fe(TMC)(CF3SO3)2, Fe(N4Py)(CF3SO3)2, and Fe(Bn-TPEN)(CF3SO3)2, and their oxo-iron(IV) complexes, [(TMC)FeIV (O)] 2+, [(N4Py)FeIV (O)] 2+, and [(Bn-TPEN)FeIV (O)]2+, werepreparedbythe literaturemethods. For example, [(TMC)FeIV (O)] 2+ was prepared by reacting Fe(TMC)(CF3SO3)2 (0.5 mM) with 1.2 equiv of PhIO (0.6 mM) in CH3CN at ambient temperature. 10-Methyl-9,10-dihydroacridine (AcrH2) was prepared from 10-methylacridinium iodide (AcrH+I-) by reduction with NaBH4 in methanol and purified by recrystallization from ethanol. AcrH+I- was prepared by the reaction of acridine with MeI in acetone, converted to the perchlorate salt (AcrH+ClO4-) by the addition of magnesium perchlorate to AcrH+I- , and purified by recrystallization from methanol. The dideuterated compound,[9,9’-2H2]-10-methylacridine (AcrD2), was prepared from 10-methy-lacridone by reduction with LiAlD4 in ether. 9-Substituted (9-alkyl or 9-phenyl) 10-methyl-9,10-dihydroacridine (AcrHR; R Me, Et, and Ph) was prepared by the reduction of AcrH I with the corresponding Grignard reagents (RMgX). AcrDPh was prepared by reducing Acr Ph with NaBD4 and purified by recrystallization from ethanol. 9-Substituted 10-methylacridinium perchlorate (AcrR ClO4; R Me, Et, and Ph) was prepared by the reaction of 10-methylacridone in dichloromethane with the corresponding Grignard reagents (RMgX) and purified by recrystallization from ethanol diethyl ether. The dideuterated compound, 1-benzyl-1,4-dihydro[4,4’-2H2]nicotinamide (BNAH-4,4’-d2), was prepared from monodeuterated compound (BNAH-4-d1) by three cycles of oxidation with p-chloranil in dimethylformamide and reduction with dithionite in deuterium oxide.
