Calculate Digit Verification of CAS Registry Number 106437-56:
(8*1)+(7*0)+(6*6)+(5*4)+(4*3)+(3*7)+(2*5)+(1*6)=113
113 % 10 = 3
So 106437-56-3 is a valid CAS Registry Number.

GENERATION OF α-ACYLCARBENIUM IONS: A NOVEL UNCATTALYSED C-C BOND FORMATION AT ROOM TEMPERATURE

Kulkarni, Gururaj C.,Karmarkar, Sanjay N.,Kelkar, Shriniwas L.,Wadia, Murzban S.

, p. 5189 - 5198 (2007/10/02)

Reactions of substituted desyl chloride 1 and 5 with phenol at room temperature in benzene results in C-alkylation.The reaction is shown to proceed through a benzylic α-acylcarbenium ion.This contention is supported by (i) the failure of this reaction with haloketones 8 and 22 and (ii) the different nature of products obtained when these haloketones were allowed to react in the presence of K2CO3.
