“…9 WP is the most active and is mainly used in organic chemistry. 10,11 BP has a layered structure similar to graphene, which can be exfoliated into single-or few-layer phosphorene. Generally, the band gap of BP is 0.3-2.0 eV (varied with the number of layers), and it has high mobility at room temperature which was also found to be thickness-dependent; the highest value up to ∼1000 cm 2 V −1 s −1 was obtained for a thickness of ∼10 nm.…”

“…However, this leads to obvious drawbacks such as toxic Cl 2 , strongly acidic conditions, hazardous and corrosive PCl 3 , and organo‐chloride waste (Scheme 1a) [8] . Furthermore, the use of molecular chlorine and PCl 3 suffers from poor selectivity and poor atom economy [9] …”

“…[8] Furthermore, the use of molecular chlorine and PCl 3 suffers from poor selectivity and poor atom economy. [9] In order to avoid the use of Cl 2 and PCl 3 , the direct transformation of P 4 into (RO) 2 P(O)H is necessary. Although the activation of P 4 is being investigated well, [10] the direct synthesis of industrially important (RO) 2 P(O)H compounds from white phosphorus is still challenging in this area.…”

Dialkyl phosphites (DAPIs), traditionally prepared from hazardous and corrosive PCl3, are the fundamental reactive starting materials used in organophosphorus chemistry. Here, a KBr‐mediated synthesis of DAPIs involving P4, alcohols and water is presented. With the use of silica gel as the catalyst, oxone as the safe oxidant, industrially important (EtO)2P(O)H, (i‐PrO)2P(O)H and (MeO)2P(O)H are prepared in 70–90% yields. Furthermore, rare metal extractant bis(2‐ethylhexyl) phosphate (D2EHPA) is obtained in 73% yield. The reaction is characterized by a complete conversion of white phosphorus. Moreover, this method can be easily adapted to large‐scale preparation.

“…The penultimate system discussed in this Minireview was reported just four months after that of Scheer and coworkers. [31] Similarly to that contribution, in their investigations Liu et al sought to exploit the reactivity of a longknown phosphorus-containing species: the anion [P(CN) 2 ] À , which was originally reported by Schmidpeter in 1977. [32] In fact, the direct synthesis of [P(CN) 2 ] À salts from P 4 had been reported before, through direct heating in the presence of KCN and 18-crown-6 (18c6).…”

Recent Breakthroughs in P₄ Chemistry: Towards Practical, Direct Transformations into P₁ Compounds

For several decades, academic researchers have been intensively studying the chemistry of white phosphorus (P 4 ) in the hope of developing direct methods for its transformation into useful P-containing products. This would bypass the hazardous, multistep procedures currently relied on by industry. However, while academically interesting P 4 activation reactions have become well established, their elaboration into useful, general synthetic procedures has remained out of reach. Very recently, however, a series of independent reports has begun to change this state of affairs. Each shows how relatively simple and practical synthetic methods can be used to access academically or industrially relevant P 1 compounds from P 4 directly, in "one pot" or even in a catalytic fashion. These reports mark a step change in the field of P 4 chemistry, and suggest its possible transition from an area of largely academic interest to one with the promise of true synthetic relevance.
