Preparation of diazoethane-2,2,2-d3: Preparation of diazoethane-2,2,2-d3. Meese, Claus O. (Fischer-Bosch-Inst. Clin. Pharmacol., Stuttgart D-7000, Fed. Rep. Ger.). J. Labelled Compd. Radiopharm., 20(9), 1047-59 (English) 1983. CODEN: JLCRD4. ISSN: 0362-4803. DOCUMENT TYPE: Journal CA Section: 23 (Aliphatic Compounds) Section cross-reference(s): 25 Alk. 64585-12-2 and 88694-63-7 are cas registry numbers of chemicals which are used as reagents here. decompn. of 4-MeC6H4SO2N(NO)CH2CD3, prepd. in 71% yield in 3 steps from D3CCN, at 0-5° for 2 min, followed by codistn. with Et2O/hexane gave D3CCHN2 (I) in 45-55% yield. Esterification of RCO2H [R = 4-O2NC6H4 (II), 4-PhC6H4, Me(CH2)16] with I gave the corresponding RCO2CH2CD3 in >96% radiochem. yield. Reaction of MeCHN2 with II in D2O/OD- gave 89% of a 1:1 mixt. of 4-O2NC6H4CO2CDRMe (R = H, D). .
