Synthesis of η-arene derivatives of chromium and molybdenum containing Lewis-acid boron substituents

The compounds Ph(CH2)3B(OH)2 I, [Ph(CH2)3BO]3 II, Ph(CH2)3B(1,2-O2C6H4) III, Ph(CH2)3BC8H14 IV (BC8H14 = 9-borabicyclo[3.3.1]nonan-9-yl), [Cr{η-Ph(CH2)3B(1,2-O2C6H 4)}(CO)3] 1, [Cr{η-Ph(CH2)3BC8H14}(CO) 3] 2, [Cr{η-Ph(CH2)3BBr2·SMe 2}(CO)3] 3, [Cr{η-Ph(CH2)4BC8H14}(CO) 3] 4, [Cr(η-Ph(CH2)4BC8H14}(CO) 2(PPh3)] 5, [Cr{η-PhCH2CH=CH2}(CO)3] 6, [Cr{η-Ph(CH2)2CH=CH2}(CO)3] 7, [Cr{η-Ph(CH2)2η-CH=CH2}(CO) 2] 8, [Cr{η-Ph(CH2)2CH=CH2}(CO) 2(PPh3)] 9, [Li(Et2O)n][Cr{η-PhCH2CH=CH 2}(CO)2{C(O)Ph}] 10, [Li(Et2O)n][Cr{η-Ph(CH2) 2CH=CH2}(CO)2{C(O)Ph}] 11, [Mo{η-Ph(CH2)3BC8H14} 2] 12 and [Cr{η-Ph(CH2)3BOC8H14}(CO) 3] 13, have been prepared and characterised. Compounds 1-5, 12 and 13 have π-donor η-arene ligands which also bear a Lewis-acid α-acceptor boron group. There was no evidence that these boron groups formed ground-state intra- or inter-molecular interactions with the Lewis base functions of the carbonyl oxygen atoms.
