75784-57-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75784-57-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,7,8 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75784-57:
(7*7)+(6*5)+(5*7)+(4*8)+(3*4)+(2*5)+(1*7)=175
175 % 10 = 5
So 75784-57-5 is a valid CAS Registry Number.

Synthesis of trans-4-Diphenylphosphinyl Stilbenes

Gloyna, D.,Alder, L.,Henning, H.-G.,Koeppel, H.,Siegmund, M.,Schleinitz, K.-D.

, p. 237 - 246 (2007/10/02)

The reaction of 4-tolyl-diphenylphosphine oxide with N-bromosuccinimide results in 4-diphenylphosphinyl benzylbromide 5 which can be easily converted to (4-diphenylphosphinyl)-benzyl triphenylphosphonium bromide 6 and (4-diphenylphosphinyl)-benzyl diphenylphosphine oxide 7, respectively.In the presence of strong bases 6 and 7 react with aromatic aldehydes 8 to the 4-diphenylphosphinyl substituted stilbenes 1.The yields depend on the nature of base and solvent.The trans configuration of 1 is determined by i.r. and 1H-n.m.r. measurements.
