“…As a result, many methods for the preparation of diverse α -aminophosphonates have been published using catalysts such as FeCl 3 [17] , [18] , [19] , CoCl 2 [20] , TaCl 5 -SiO 2 [21] , InCl 3 [22] and TiO 2 [23] . Furthermore, the ultrasound irradiation and microwave are considered as a successful alternative protocol to synthesis α -aminophosphonates in good yields [24] , [25] , [26] , [27] . As part of our series of research in our laboratory [28] , [29] , [30] , we recently reported investigations on the course of microwave irradiations applied in organic synthesis which has several advantages such as easy workup, reducing the reaction time from days to minutes, cleaner products, higher yields and environmentally benign which attract and encourage the organic chemists to use this method [31] , [32] , [33] .…”
