In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called A Biphilic Phosphetane Catalyzes N-N Bond-Forming Cadogan Heterocyclization via PIII/PV=O Redox Cycling, published in 2017-05-24, which mentions a compound: 707-61-9, Name is 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide, Molecular C11H13OP, HPLC of Formula: 707-61-9.

A small-ring phosphacycle, 1,2,2,3,4,4-hexamethylphosphetane, is found to catalyze deoxygenative N-N bond-forming Cadogan heterocyclization of o-nitrobenzaldimines, o-nitroazobenzenes, and related substrates in the presence of hydrosilane terminal reductant [e.g., I → II (83%) in presence of phosphine oxide III.[O] and PhSiH3]. The reaction provides a chemoselective catalytic synthesis of 2H-indazoles, 2H-benzotriazoles, and related fused heterocyclic systems with good functional group compatibility. On the basis of both stoichiometric and catalytic mechanistic experiments, the reaction is proposed to proceed via catalytic PIII/PV=O cycling, where DFT modeling suggests a turnover-limiting (3+1) cheletropic addition between the phosphetane catalyst and nitroarene substrate. Strain/distortion anal. of the (3+1) transition structure highlights the controlling role of frontier orbital effects underpinning the catalytic performance of the phosphetane.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Structure of diene-phosphonous dihalide addition products and of derived phospholenes and phospholene oxides, published in 1968, which mentions a compound: 707-61-9, mainly applied to DIOLEFINS; DIOLEFINS PHOSPHENOUS DIHALIDE; DIHALIDE; PHOSPHOLENES; PHOSPHENOUS DIHALIDE CYCLOADDUCTS; CYCLOADDUCTS DIOLEFINS PHOSPHENOUS, Recommanded Product: 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide.

The cycloadducts of MePCl2 and butadiene, isoprene, 3,4-dimethylbutadiene, or piperylene give rise to 3-phospholene oxides on hydrolysis and 3-phospholenes (I) on reduction with Mg. The cycloadduct from butadiene also contained the 3-phospholene ring. The 3-phospholene oxides may be caused to rearrange to 2-phospholene oxides either thermally or by refluxing aqueous base. Acid treatment was effective only for rearranging the 3-Me derivative The 3,4-di-Me derivative resisted rearrangement conditions. PhPBr2 (synthesized by a new method from PhP(O)(OH)Cl and PBr3) also gave an adduct with isoprene shown by N.M.R. studies to contain the 3-phospholene ring, which was preserved in the oxide and phospholene. However, the isoprene-PhPCl2 adduct contained the 2-phospholene ring; the derived oxide and phospholene were also the 2-isomers. Independent syntheses of the isomeric 1-phenyl-3-methylphospholene oxides confirmed the assignments. The adduct from piperylene and PhPBr2 also gave on hydrolysis the 3-phospholene oxide, while that from PhPCl2 gave the 2-isomer. 26 references.
