Hydrazine → HCID 12901376, compound

Participants

Reaction Steps

A mixture of 8 g (30 mmoles) of 2-(ethoxycarbonyl)-ethyltrimethylstannane (compound 47), 5 ml of 95% hydrazine (150 mmoles) in 10 ml of ethanol was refuxed for 2 hours. The volatiles were removed at reduced pressure. Distillation of the crude product afforded 5.26 g of 2-(hydrazinocarbonyl)ethyltrimethylstannane, b.p. 92°-98° C. (0.07 mm), compound 42 of Table I. The infrared spectrum of the distillate showed the following characteristic absorptions: 3300 cm-1 (N-H), 1660 cm-1 and 1530 cm-1 ##STR22## and 760 cm-1 (--Sn(CH3)3). A gas chromatogram of the sample showed a single peak on a 6'×1/8" commercially obtained column packed with 10% on silicone gum rubber on silanized diatomaceous earth. The NMR spectrum exhibited the following proton absorptions: a broad singlet at 752 Hz (1 proton) assigned to N-H, a singlet at 388 Hz (2 protons) assigned to NH2, a triplet centered at 235 Hz (2 protons) assigned to ##STR23## a triplet centered at 98 Hz (2 protons) assigned to CH2 -Sn, and a singlet centered at 6 Hz (9 protons) assigned to Sn(CH3)3.
