Abstract

The reaction of I (CH 2) 2CHCH 2O and an excess of LiI with [Mo (CNMe)(CO) 2 (η-C5H5)]− gives crystallographically characterized cis-[MoI (CO) 2= C (CH 2) 2CH (CH 2OH) N Me (η- C5H5)]. This reacts with C5H5NO to give a high yield of the γ-lactam Me NC (= O) CH 2CH 2C H (CH 2OH). The corresponding reaction of I (CH 2) 3CHCH 2O with excess LiI and [Mo (CNMe)(CO) 2 (η-C5H5)]− gives cis-[Mo (CO) 2η 2-C (CH 2) 3CH (CH 2I) O NHMe](also ...
