Aluminum picrate

Aluminum Picrate. [C6H2(N02)30] 3A1 mw 711.31 N 17.73% mp, fuses above 100° and explds on further heating. Can be prepd by the prolonged heating of one of its hydrates (such as di-,tetra-,deca-,or hexadeca-hydrate)to 100°. 

Aluminum Picrate (Basic). [C6 H2(N02)3O] 2 A10H.7H20 mw 530.35, N 15.85% reddish to pale yel needles which, when heated to 80°, change to the tetrahydrate, a pale yel powd which, on heating, decomps without expldg Ref Colver (1938), 331...

Nitrated cresols form a number of salts, by interaction with inorganic compds. These salts are called Cresylates. They possess props similar to those of Picrates, except that they are less powerful less sensitive expls than Picrates. Colver (Ref 4) gives a fairly complete list of these compds, and Kast (Ref 3) describes their props. Some of the more important Cresylates are Aluminum Trinitrocresylate (Basic), HO.A1-(C H4N30 )2+ 5H20 pale reddish ndls, mp defgr above 100° sol in w ale resembles the corresponding picrate in other props (Refs 1 4).

The reduction of the phenolbetaine VIII with sodium borohydride or lithium aluminum hydride affords the alkaloid ( )-ophiocarpine (XIV R = OH). In contrast, reduction of XI with zinc-acetic acid gives a mixture of two isomers having the empirical formula, C20H21O4N, isomer-a (mp 169°-171° picrate, mp 181°-187°), and isomer-b (mp... 

S. sarmentosum contains two liquid alkaloids which are separated by fractional crystallization of the picrates. The least soluble picrate (CigHanOgNi), m.p. 159°, proved to be identical with the picrate of synthetic d(-methylisopelletierine (86). The more soluble picrate (C1BH22O8N4), m.p. 125°, is that of an optically active base C9H19ON, [a] 25.0 (abs. ethanol). On the assumption that this new base was the dihydro derivative of. A -methyl-isopelletierine (.A -methyl-l-(2-piper-idyl)-2-propanol), di-methylisopelletierine was reduced with lithium aluminum hydride and the product converted to the picrate. The two diastereoisomeric forms separated into an oily picrate and a crystalline picrate, m.p. 126° (86). The base recovered from this picrate could not be resolved (93). 

Virosecurinine possessed the same molecular formula as securinine and showed no N- or 0-methyl groups. Its IR and UV spectra indicated the presence of an extended a,)5-unsaturated y-lactone moiety. On hydrogenation over palladium in benzene solution, virosecurinine gave dihydrovirosecurinine (109) and an oily aminolactone (110) characterized as its crystalline picrate (mp 215°, dec) and A-acetyl derivative (mp 166-166.5°). Appropriate IR and UV spectra were observed for the two products 109 and 110. Lithium aluminum hydride reduction... 

XLVII). Lithium aluminum hydride reduction yielded (+ )-isoretro-necanol (VII+ X) (picrate, mp 188°-189° benzoate picrate, mp 130°-131°).
