Organophosphorus chemistry is the scientific study of the synthesis and properties of organophosphorus compounds, which are organic compounds containing phosphorus. [1] . They are used primarily in pest control as an alternative to …

Organophosphates are a class of compounds encompassing a number of distinct but closely related function groups. These are primarily the esters of phosphoric acid and can be mono‑esters, di‑esters or tri‑esters depending on the number of attached organic groups (abbreviated as 'R' in the image below).

2023年11月12日 · Organophosphates are chemical compounds formed through the esterification process involving phosphoric acid and alcohol. These chemicals serve as primary components in herbicides, pesticides, and insecticides and have extensive …

Organophosphorus compounds are organic chemicals derived from phosphoric acids, commonly used as pesticides. They can also include nerve agents and have variable structures, with the substituents attached to the phosphorus influencing their toxicity.

Organophosphorus compounds generally contain both sulfur and phosphorus linked to carbon atoms. Their discovery was a by-product of the development of nerve gases. The group includes parathion, malathion, dimethoate, diazinon, and chlorfenvinphos. They are used as herbicides, insecticides, and fungicides.

有机磷化合物（Organophosphorus Compound）含碳-磷键的化合物或含有机基团的磷酸衍生物 [1]。 有机磷化合物的磷原子有空的d轨道， 价态 较多，主要有以下几类： ①三配位磷化合物。 为sp3 (不等性)杂化三角锥构型，磷原子带孤对电子。 三价磷化合物具有亲电性、双亲性和亲双烯的反应特性，反应时经常能形成很强的PO键。 例如，三烷基膦和亚磷酸三烷基酯都是三价磷化合物。 由于磷原子的体积较大， 电负性 较小，三烷基膦的亲核性和碱性比三烷基胺大。 有3个不 …

2019年2月1日 · Filling the gap for an up-to-date reference that presents the field of organophosphorus chemistry in a comprehensive and clearly structured way, this one-stop source covers the chemistry,...

2013年12月20日 · The term organophosphorus (OP) compounds refers to any group of organic chemicals that contain phosphorus. The most predominant valances of phosphorus are 3 and 5. The majority of OP compounds (OPs) with environmental and industrial applications are of the pentavalent types.
