Also for the phosphepine system [108], benzannulation leads to interesting targets. Namely, the thermal lability of the transition-metal-complexed 3H-benzophosphepine 33 was explored by Lammertsma et al. for the synthesis of a variety of organophosphoruscompounds by means of [1

Introduction
Organophosphoruscompounds have found a wide range of application in the areas of industrial, agricultural, and medicinal chemistry owing to their biological and physical properties as well as their utility as synthetic
the utility of surface-mediated reactions for the synthesis of organophosphoruscompounds, [37][38][39][40][41][42][43][44][45][46][47][48] we report a new method for the preparation of phosphorothioates by reaction of diethyl phosphite with alkyl halides in the presence of a mixture of ammonium
group (hard electrophilic center) gives the O-acylation product.
As a part of our efforts to explore the utility of surface-mediated reactions for the synthesis of organophosphoruscompounds, [16][17][18] herein we report a new method for the preparation of phosphorothioates by reaction of diethyl
