Phosphaindole derivative, benzophosphaindole derivative and preparation methods thereof

The invention discloses a phosphaindole derivative, a benzophosphaindole derivative and preparation methods thereof. The preparation method of the phosphaindole derivative comprises the following steps: alkyne, a phosphorus reagent, a copper catalyst and

Synthesis of 2,3-dihydro-1-phenylbenzo[b]phosphole (1-phenylphosphindane) and its use as a mechanistic test in the asymmetric appel reaction: Decisive evidence against involvement of pseudorotation in the stereoselecting step

Racemic 2,3-dihydro-1-phenylbenzo[b]phosphole was obtained by reduction of 1-phenylbenzo[b]phosphole-1-oxide, itself derived by ring-closing metathesis of phenylstyrylvinylphosphine oxide. The title compound was then reoxidized under asymmetric Appel cond

Studies on seven-membered heterocycles. XXXIV. Syntheses and reactions of 1-benzosilepines, 1-benzogermepines, 1-benzophosphepines, and 1-benzarsepines

Flash vacuum pyrolysis of 2a,7b-dihydrocyclobuta[b]-1-benzometalloles (6a-e), prepared from the corresponding 1-benzometalloles (3) containing Si, Ge, P, or As via three steps, resulted in valence isomerization with ring-opening to give 1,1-dimethyl-1-benzosilepine (7a), 1-methyl-1-phenyl-1-benzosilepine (7b), 1,1-dimethyl-1-benzogermepine (7c), 1-phenyl-1-benzophosphepine 1-oxide (7d), and 1-phenyl-1-benzarsepine 1-oxide (7e). The oxides (7d,e), on treatment with trichlorosilane, underwent deoxygenation to afford 1-phenyl-1-benzophosphepine (7f) and 1-phenyl-1-benzarsepine (7g). The 1-benzometallepines (7a-g) thus obtained are hitherto unknown heterocyclic ring compounds, and their thermal stabilities and several reactions were examined.

A Versatile Synthetic Route to 1-Benzometalloles involving the First Examples of Several C-Unsubstituted Benzometalloles

The group 14 (Si, Ge, Sn), group 15 (P, As, Sb, Bi) and group 16 (S, Se, Te) (2-trimethylsilyl)-1-benzometalloles 5 have been prepared from phenylacetylene via three steps and converted into the corresponding C-unsubstituted benzometalloles 7 by detrimethylsilylation.

PRELIMINARY RESULTS IN CYCLOADDITION OF DIPHENYLNITRILIMINE TO PHOSPHINDOLE OXIDES

Diphenylnitrilimine cycloaddition reactions to two phosphindoles oxides are regiospecific ans stereospecific.The approach of the dipole occurs from the less hindered diastereotopic side of the dipolarophile.

ON SOME CHEMICAL PROPERTIES OF 1-PHENYLPHOSPHINDOLE

The title compound 5 can be easily synthesized by combination of two published procedures.It undergoes quantitative lithium cleavage of the exocyclic P-Ph bond, and phosphorus substituent exchange by reaction with t-butyllithium.The phosphindolyl anion di
