5-methyl-5-phenyl-5H-benzo[b]phosphindolium iodide is a complex organic compound with the chemical formula C18H16IP+. It is a derivative of benzo[b]phosphindole, featuring a methyl group at the 5-position and a phenyl group at the 5-position as well. The compound is characterized by its unique structure, which includes a phosphorus atom bonded to a benzene ring, creating a phosphindole framework. The iodide ion (I-) is associated with the positively charged phosphindolium cation (C18H16IP+), forming an ionic compound. This chemical is of interest in the field of organic chemistry, particularly in the study of phosphorus-containing heterocycles, and may have potential applications in the development of new materials or as intermediates in synthetic chemistry.

2751-93-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2751-93-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,5 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2751-93:
(6*2)+(5*7)+(4*5)+(3*1)+(2*9)+(1*3)=91
91 % 10 = 1
So 2751-93-1 is a valid CAS Registry Number.

The mechanism of the first step of the Mitsunobu reaction

Camp, David,Von Itzstein, Mark,Jenkins, Ian D.

, p. 4946 - 4948 (2015)

Previous DFT calculations employing phosphine (PH3) and dimethyl azodicarboxylate showed that a cyclic O,N-phosphorane was energetically favored relative to betaine formation. In this study strong experimental support for the formation of the phosphorane is described. The question of whether betaine formation occurs via nucleophilic attack of the phosphine on the azodicarboxylate as has been previously assumed, or via a [4+2] cycloaddition (cheletropic) reaction to give the O,N-phosphorane, followed by ring-opening to give the betaine has not been resolved. An answer to this intriguing question is provided.

Observation of a betaine lithium salt adduct during the course of a wittig reaction

Neumann, Robert A.,Berger, Stefan

, p. 1085 - 1087 (1998)

A stable betaine lithium salt adduct is observed during the course of a Wittig reaction. The stabilization of this adduct has been achieved by complexation with lithium ions and by using the chelating effect of pyridyl ligands. Dynamic NMR spectra are obs
