The chemical compound "10,11-Dimethyl-12-phenyl-8,12-bis(trimethylsilyl)-10,11-diaza-1,9-diphosphatricyclo<7.2.1.02,7>dodeca-2,4,6-trien" is a complex, cyclic molecule with a unique structure. It features a tricyclic framework with a phosphorus atom at positions 10 and 11, both of which are connected to a nitrogen atom, forming a diaza group. The molecule also includes two methyl groups at positions 10 and 11, and a phenyl group at position 12. Additionally, it has two trimethylsilyl groups attached to the phosphorus atoms at positions 8 and 12, which contribute to the molecule's stability and reactivity. 10,11-Dimethyl-12-phenyl-8,12-bis(trimethylsilyl)-10,11-diaza-1,9-diphosphatricyclo<7.2.1.02,7>dodeca-2,4,6-trien is characterized by its intricate arrangement of atoms and the presence of both phosphorus and silicon, making it an interesting subject for study in the field of organophosphorus chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 84440-37-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,4,4 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84440-37:
(7*8)+(6*4)+(5*4)+(4*4)+(3*0)+(2*3)+(1*7)=129
129 % 10 = 9
So 84440-37-9 is a valid CAS Registry Number.

Low Coordinated Phosphorus Compounds. 12. Diels Alder Reactions of Phosphaalkenes

Appel, Rolf,Korte, Stephan,Halstenberg, Mechthild,Knoch, Falk

, p. 3610 - 3617 (2007/10/02)

N,N'-Diorganylhydrazines 1a - e react with chlorophosphane (2) to yield the diazadiphosphahexadienes 3a - e as non isolable intermediates. 3a - e give an intramolecular Diels Alder reaction with participation of two PC double bonds to form the tricyclic compounds 5a - e.The α-C-branched hydrazines 1f - h yield the phosphaalkenes 6f - h via mono-substitution.These surprising results are confirmed by spectroscopy as well as partly by X-ray structure determination.This observation is another evidence for the relationship between the PC double bond and the olefin systems.
