34872-49-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 34872-49-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,7 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 34872-49:
(7*3)+(6*4)+(5*8)+(4*7)+(3*2)+(2*4)+(1*9)=136
136 % 10 = 6
So 34872-49-6 is a valid CAS Registry Number.

Platinum(0) complexes of cyclic alkynes and allenes from base-induced dehydrohalogenation of bromocycloalkenes

Lu, Zheng,Abboud, Khalil A.,Jones

, p. 1471 - 1474 (2008/10/08)

Treatment of 1-bromocycloheptene or a mixture of 1-, 2-, and 3-bromocycloheptatrienes with t-BuOK in the presence of (Ph3P)3Pt has been confirmed to lead to predominant formation of (Ph3P)2Pt π-complexes of the corresponding cyclic allenes. In contrast, reaction of these same halides and 1-bromocyclohexene with LDA in THF in the presence of (Ph3P)3Pt leads exclusively to (Ph3P)2Pt complexes of the corresponding cyclic akynes. These reactions provide the first metal complexes of cycloheptadienynes and a convenient alternate method for the preparation of Pt(O) complexes of cyclohexyne and cycloheptyne. The mechanism of formation of the complex of 1,2-cycloheptadiene is briefly discussed and an X-ray crystal structure of one of the cyclheptadienyne complexes is reported.
