16883-45-7 Usage

Uses

Reactant for:Preparation of iridium tetrahydride complexes bearing a tridentate pincer-type bis(phosphino)silyl ligandReduction reactions (reducing agent)

Purification Methods

Recrystallisation of the borohydride from H2O three times yields ca 94% pure compound. Dry in high vacuum at 100o for 3hours. The solubility in H2O is 48% (20o), 61% (40o), and in EtOH 0.5% (25o) and MeCN 0.4% (25o). It decomposes slowly in a vacuum at 150o, but rapidly at 250o. The rate of hydrolysis of Me4N.BH4 (5.8M) in H2O at 40o is constant over a period of 100hours at 0.04% of original wt/hour. The rate decreases to 0.02%/hour in the presence of Me4NOH (5% of the wt of Me4N.BH4). [Banus et al. J Am Chem Soc 74 2346 1952, Beilstein 4 IV 148.]

Check Digit Verification of cas no

The CAS Registry Mumber 16883-45-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,8 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 16883-45:
(7*1)+(6*6)+(5*8)+(4*8)+(3*3)+(2*4)+(1*5)=137
137 % 10 = 7
So 16883-45-7 is a valid CAS Registry Number.

Pigments of fungi. LXIII Synthesis of (1S,3R)- and (1R,3S)-austrocortilutein and the enantiomeric purity of austrocortilutein in some Australian Dermocybe toadstools

Elsworth, Catherine,Gill, Melvyn,Raudies, Evelin,Ten, Abilio

, p. 41 - 46 (2000)

The naturally occurring tetrahydroanthraquinones (1S,3R)- and (1R,3S)-austrocortilutein (1b) and (1d), respectively, are synthesized for the first time in enantiomerically pure form by Diels-Alder cycloaddition between the functionalized butadiene derivative (4) and the corresponding monochiral trans-1,3-dihydroxy-1,2,3,4-tetrahydro-5,8-naphthoquinone (5a) or (5b), themselves derived from citramalic acid. Separation of the four stereoisomeric austrocortiluteins by using h.p.l.c. over a chiral stationary phase reveals that the enantiomeric purity of the (1S,3S)-and (1R,3R)-quinones (1a) and (1c) varies from species to species whereas the (1S,3R)-isomer (1b) is, in the five cases examined, enantiomerically pure.
