Calculate Digit Verification of CAS Registry Number 96917-81:
(7*9)+(6*6)+(5*9)+(4*1)+(3*7)+(2*8)+(1*1)=186

Synthesis and Characterization of Di-disubstituted Phthalocyanines

Young, Joseph G.,Onyebuagu, William

, p. 2155 - 2159 (1990)

An improved approach to the synthesis of di-disubstituted phthalocyanines from two different phthalyl precursors is described.The method combines substituted 1,3-diiminoisoindoles and 6/7-nitro-1,3,3-trichloroisoindolenine to synthesize phthalocyanine.The method can be applied to the synthesis of hydrogen and metallo phthalocyanine.The yields are variable, ranging from 17percent to 72percent depending on the substituents.
