42506-03-6 Usage

Uses

9-Chloro-9-phenylxanthene was used in the preparation of (1S,5S,6R,8S)-6-[(allyloxycarbonyl)oxy]-5-(trifluoroacetamido)-8-[9′-(9′-phenylxanthenyl)oxy]-2-oxabicyclo(3.2.1)octane.

Purification Methods

A possible impurity is 9-hydroxy-9-phenylxanthene. If the material contains a lot of the hydroxy product, then boil 10g of it in CHCl3 (50mL) with redistilled acetyl chloride (1mL) until liberation of HCl is complete. Evaporation leaves the chlorophenylxanthene as the hydrochloride which on heating with *benzene loses HCl; and on adding pet ether prisms of chlorophenylxanthene separate and contain 0.5mol of *benzene. The *benzene-free compound is obtained on drying, and it melts to a colourless liquid. [Gomberg & Cone Justus Liebigs Ann Chem 370 142 1909.] The 9-phenylxanthyl group is called “pixyl” and is a good protecting group [Chattopadhyaya & Reese J Chem Soc, Chem Commun 639 1978, Beilstein 17 III/IV 1704.]

Check Digit Verification of cas no

The CAS Registry Mumber 42506-03-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,0 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 42506-03:
(7*4)+(6*2)+(5*5)+(4*0)+(3*6)+(2*0)+(1*3)=86
86 % 10 = 6
So 42506-03-6 is a valid CAS Registry Number.

REACTIVITIES OF HETEROAROMATIC CATIONS CONTAINING A GROUP VIB ELEMENT IN NUCLEOPHILIC REACTIONS. REACTIONS OF 9-PHENYL-XANTHYLIUM, -THIOXANTHYLLIUM, AND -SELENOXANTHYLIUM SALTS WITH AMINES, SODIUM PHENOLATE, AND SODIUM BENZENETHIOLATE

Reactions of 9-phenylchalcogenoxanthyllium salts (1a-c) with some nucleophiles have been examined in order to find the differences in reactivity in nucleophilic reactions.The chalcogenoxanthylium salts (1a-c) react with aniline in ether to give 9-anilino-9-phenylchalcogenoxanthenes (7a-c).However, in acetonitrile the xanthylium salt (1a) affords N,4-bis(9-phenylxanthen-9-yl)aniline (9a) together with the anilinoxanthene (7a) (at room temperature) or 9-(p-aminophenyl)-9-phenylxanthene (8a) (at reflux) and the sulphur (1b) and the selenium derivative (1c) affords only the anilino derivatives (7b,c), respectively.In the reactions with sodium phenolate, the thioxanthylium salt (1b) gave 9-phenoxy-9-phenylthioxanthene (13b), whereas the oxygen (1a) and the selenium congener (1c) gave O,4-bis(9-phenylchalcogenoxanthen-9-yl)phenols (15a,c) together with the 9-phenoxy derivatives (13a,c), respectively.The results show that the thioxanthylium salt (1b) gave the products formed on attack by the heteroatom of the ambident nucleophiles and the ratio of the carbon attack increased in the order (1a) > (1c) > (1b).This difference would be attributable to the properties of carbocations at the 9-position in the heteroaromatic cations (1a-c).
