34999-47-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 34999-47-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,9,9 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 34999-47:
(7*3)+(6*4)+(5*9)+(4*9)+(3*9)+(2*4)+(1*7)=168
168 % 10 = 8
So 34999-47-8 is a valid CAS Registry Number.

Palladium-catalyzed direct oxidative ortho-acylation of anilides with toluene derivatives

Weng, Jianquan,Yu, Zhiqin,Liu, Xinghai,Zhang, Guofu

, p. 1205 - 1207 (2013)

Direct oxidative ortho-acylation reaction of anilides with toluene derivatives in the presence of palladium acetate using tert-butyl hydroperoxide as an oxidant was developed. A broad range of diaryl ketones was obtained in good to excellent yields (up to 95%). The plausible mechanism was also proposed.

A one-pot process for palladium catalyzed direct C-H acylation of anilines in water using a removable ortho directing group

Szabo, Fruzsina,Simko, Daniel,Novak, Zoltan

, p. 3883 - 3886 (2014/01/06)

A new mild, practical method for the synthesis of aminobenzophenone derivatives through a three step one-pot reaction sequence involving acylation of anilines, palladium catalyzed cross-dehydrogenative coupling of the formed anilides and the hydrolytic cleavage is reported. The full reaction sequence was performed under aqueous conditions.

Palladium-catalyzed direct ortho -acylation through an oxidative coupling of acetanilides with toluene derivatives

Yin, Zhangwei,Sun, Peipei

, p. 11339 - 11344 (2013/02/23)

A facile ortho-acylation of acetanilides by a Pd-catalyzed oxidative C-H activation was developed in which low toxic, stable, and commercially available toluene derivatives were first used as acylation reagents by a tandem reaction to form o-acylacetanili
