“…Our thoughts then turned to the use of microwave irradiation instead of ball-milling, as this could potentially reduce the reaction time dramatically. Should this methodology prove successful, this could provide a rapid and easy method of creating similar heterosubstituted boroles and borinines as a large variety of boronic acids are commercially available, and others can be created using Grignardtype procedures [9,10]. These reagents could then be utilized further in SuzukieMiyaura or Petasis-type reactions [11].…”

“…The first synthesis from an organozinc reagent preceded general acceptance of Avogadro's hypothesis [1], and was superseded nearly a century ago by the now standard preparation from Grignard reagents [2,3]. Hydroboration has Boronic Acids.…”

“…The first synthesis from an organozinc reagent preceded general acceptance of Avogadro's hypothesis [1], and was superseded nearly a century ago by the now standard preparation from Grignard reagents [2,3]. Hydroboration has been known for half a century [4], and several variants are particularly useful for boronic ester synthesis [5,6], including several asymmetric examples [7].…”

“…Σύμφωνα με τη βιβλιογραφία, 31 το στάδιο αυτό θα ήταν επιτυχές με προσθήκη του φαινυλοβορονικού οξέος 188 (1 eq) σε διάλυμα της ένωσης 466 με THF, εν συνεχεία προσθήκη υδατικού διαλύματος Na 2 CO 3 (2M) και καταλυτικής ποσότητας του παλλαδιακού συμπλόκου Pd(PPh 3 ) 4 , με ακόλουθη θέρμανση του μίγματος της αντίδρασης σε συνθήκες κάθετης επαναρροής του διαλύτη. Ωστόσο εφαρμογή των ανωτέρω συνθηκών δεν παρείχε τα αναμενόμενα αποτελέσματα καθώς η πρώτη ύλη παρέμενε αναλλοίωτη.…”
